As a pharmacist, educator, and writer, I’ve been getting all kinds of questions about the COVID-19 vaccine. Whether you’re wondering if the vaccine can make you sick, how it works, or who should get vaccinated, I’m here to give you the answers you’re looking for.

First, let’s talk about something many of us have experienced: COVID-19 pandemic-induced stress.

Stress during the pandemic

Pandemic-induced stress is real. I often find myself pouring through research from every corner of the internet, including journal articles and resources that my peers send me about COVID-19. The truth is, it can get overwhelming, and feeling overwhelmed can quickly turn into undue stress.

While you’re waiting in the invisible line-up for a COVID-19 vaccine and managing a new way of life, the build-up of stress can take a toll on you. Men’s mental health is often ignored and is something many of us are trying to deal with right now. 

If you have an activity that brings you a sense of calm or have ways to relax, try to keep them a part of your daily routine. If you’re looking for tips and resources to manage stress and mental health, check out the Mental Health First Aid COVID-19 Self-Care & Resilience Guide. British Columbia’s virtual mental health support during COVID-19 and BC211 are also great resources.

Sometimes having access to the right information in one place can help reduce the stress associated with uncertainty regarding the pandemic and the COVID-19 vaccines developed to combat this virus.

Who should get the COVID-19 vaccine?

Almost everyone should get the COVID-19 vaccine when it’s their time to do so. Immunize BC says that if you do not have any allergies to the ingredients in a COVID-19 vaccine and have not experienced a life-threatening reaction (anaphylaxis) to a previous dose of the COVID-19 vaccine, you can get vaccinated.

You’ll also need to be over the minimum age requirement and not have symptoms of COVID-19 at the time of vaccination. “With every person who receives a vaccine, our entire province becomes that much safer,” says Dr. Bonnie Henry, Provincial Health Officer for British Columbia.

Vaccine exceptions

Children and youth

Children and youth under the age of 16 are not approved to receive the Pfizer-BioNTech COVID-19 vaccine at this time, while those under the age of 18 are not approved to receive the Moderna, Johnson & Johnson, or AstraZeneca/Oxford, COVID-19 vaccine at this time.

Pregnant, breastfeeding, and/or immunocompromised

Currently, there is not enough information to determine if a person who is pregnant or breastfeeding or who is immunocompromised should or should not get vaccinated. People who fall into these groups can get help making this decision by speaking with a local healthcare provider they trust.


If you have a severe allergy to any component of the vaccine, to polyethylene glycol, or have shown an immediate allergic response to polysorbate (which has cross-reactivity with polyethylene glycol) you should speak to your healthcare provider to determine if the COVID-19 vaccine is appropriate for you.

Be part of the herd – We’re in this together

Now that you know there are some people who may not be able to get the vaccine, it’s important that everyone who can get vaccinated does get vaccinated. This way, we can work together to protect the people who can’t get the vaccine. That’s called herd immunity.

In a really, really basic sense, it’s kind of like when you’re watching National Geographic and you see lions on the hunt and then the bigger, stronger elephants create a shield around the smaller elephants to protect them from the attack because the smaller elephants could never protect themselves on their own. 

Herd immunity, described by the World Health Organization, “is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection.” 

Alright, now here are the answers to the “Top COVID-19 Vaccine Questions”:

Coivd Vaccine
How to get your COVID-19 vaccination in your province or territory:

Ongoing distribution concerns may have delayed when we can get our vaccines. However, things are improving. It’s very important to keep up-to-date with the latest information in your province or territory so you can be ready to book your appointment as soon as your region announces you can do so. The Government of Canada’s Vaccines for COVID-19 page offers quick links to relevant information you can use right now.

Can you get COVID from the COVID-19 vaccine?

No. You cannot get infected with COVID from the COVID-19 vaccine. Since the vaccines currently available in Canada are not live vaccines, they cannot cause the disease they are designed to protect you from.

Are there side effects you can get from the COVID-19 vaccine?

While there are some side effects people may experience from the COVID-19 vaccine, they’re often mild and go away within a few days. The most common side effects are redness, soreness, or swelling where you received the injection, as well as feeling tired (fatigue), headache, fever or chills, body aches or sore joints. Some people may not experience any side effects at all, while other people might experience one or more side effects.

How is the COVID-19 vaccine administered? 

The COVID-19 vaccines available in Canada, at this time, are administered as an intramuscular injection. Most people will get the injection in their arm, like a typical, routine vaccine. Some vaccines are given in two doses and others are given as one dose.

Each dose of the Pfizer-BioNTech COVID-19 vaccine, Moderna COVID-19 vaccine, and AstraZeneca/Oxford COVID-19 vaccine are given several weeks apart. The time between doses may vary across Canada. 

The Johnson & Johnson COVID-19 vaccine is given in one dose.

How does the COVID-19 vaccine work?

The first dose helps the immune system create a response against the virus, and the second dose further boosts the immune response, which helps ensure long-term protection. Vaccines that come in a single dose aim to create a response strong enough at one time so that a second dose is not required.

Both the BioNTech and Moderna COVID-19 vaccines are messenger RNA (mRNA) vaccines. These vaccines contain instructions to make a protein that is found on the surface of the virus that causes COVID-19. Using our body to make the protein triggers our immune system to create antibodies against it.

The Johnson & Johnson and AstraZeneca/Oxford COVID-19 vaccines are viral vector vaccines. These vaccines use the harmless adenovirus as a delivery system to help bring important protein-building instructions into our cells. With this information, our body can make the specific protein it needs in order to trigger an immune response. Then our immune systems will have effectively created antibodies against the virus.

To clear things up, the adenovirus used in these vaccines are viruses that can cause the common cold and have been used for decades as a way to deliver instructions for proteins.

If the real virus ever enters our body, in the future, our body will trigger an immune response in order to fight the infection regardless of which vaccine we received.

How protected are you after the first dose of the vaccine?

It’s always important to receive both vaccine doses in a series if they are designed to be delivered that way in order to reap the maximum benefit and long-term effectiveness.

After the first dose of the Pfizer-BioNTech COVID-19 vaccine, it was shown to be up to 52% effective vs. up to 95% effective after the second dose.

After the first dose of the Moderna COVID-19 vaccine it was shown to be up to 80.2% effective vs. up to 95.6% effective after the second dose.

After the first dose of the AstraZeneca/Oxford COVID-19 vaccine, it was shown to be up to 62% effective vs. up to 70-80% effective after the second dose.

The Johnson & Johnson COVID-19 vaccine is a one-dose vaccine that showed an overall efficacy of up to 66% and up to 85% efficacy in severe cases.

Can you still carry and spread the virus if you’ve been vaccinated?

After you get vaccinated, it’s still possible that you can get infected and then spread COVID-19. This could be because you were infected just prior to getting the vaccine or because you got infected during the period you received the vaccine to when the vaccine developed enough immunity in your body. Usually, the vaccine takes a few weeks to help your body develop its defences.

Is it better to get the COVID-19 vaccine or get the actual virus and to build your immunity?

The best way to protect yourself from the COVID-19 virus is to get vaccinated. While not everyone who is infected with the COVID-19 virus will die, many people can get severely ill, may be hospitalized, and may even experience permanent organ damage.

The risk of trying to build our own immunity through exposure to the virus vs. getting vaccinated isn’t worth the damage it can do to your overall health. Simply put, getting the COVID-19 vaccine is much safer than risking infection from the actual virus.

Can you get the COVID-19 vaccine during Ramadan?

Yes, you can get the COVID-19 vaccine during Ramadan. Getting this vaccine will not “break” your fast. Since the COVID-19 vaccine is delivered as an intramuscular injection and does not provide any nutritional support, it is not considered sustenance or food, making it permissible to get during Ramadan. The National Muslim Task Force on COVID-19 issued a press release on April 6th, 2021, outlining how to have a safe Ramadan and clarification that the COVID-19 vaccines currently available are halal.

How much does the COVID-19 vaccine cost?

The Government of Canada makes it clear that the COVID-19 vaccine will be free for all Canadians with an added commitment for low and middle income economies around the world to also have access to these vaccines.

For our neighbours to the South, the CDC mentions that Americans will be able to receive the vaccine at no cost. Providers of the vaccine can charge an administration fee; however, no American will be denied the COVID-19 vaccine if they cannot afford the vaccine administration fee. 

When can you get the COVID-19 vaccine?

Depending on your age, type of work you do, and where you live, your ability to get the COVID-19 vaccine will be different. Across Canada, the plan to distribute vaccines focuses on reaching residents and staff of shared living settings that provide care for seniors, adults age 70 and older, with priority given to adults over 80 years of age, healthcare workers who have direct contact with patients, and adults in Indigenous communities.

British Columbia has designed a plan with projected dates for whom in their province will receive the COVID-19 vaccine. The province will focus on certain priority groups and aims to make vaccinations available to members of the general public, aged 18-59, from July to September 2021. Dr. Bonnie Henry expects to have vaccines available to everyone by next fall.

After you’ve been vaccinated

Remember, even after being vaccinated, it is important to practice physical distancing, hand hygiene and to continue wearing face masks to stop any potential spread of this virus. For more information, check out the BC Center for Disease Control.

COVID-19 additional support

While trying your best to help others, it’s equally important to watch out for yourself and monitor your stress and overall wellness. Oftentimes, stress is linked to financial uncertainty. One way to manage this uncertainty is to take advantage of financial support programs created by the Government of Canada and the Government of British Columbia. Some of these financial support benefits are listed below:

Lastly, if anyone asks you if the COVID-19 vaccines can change your DNA, just let them know that would be pretty wild. These vaccines cannot alter your DNA.
