As the pandemic continues, public health experts are urging everyone to get vaccinated and to get a booster dose of the COVID-19 vaccine, which can help increase one’s immune response to the virus.
McMaster University is hosting a vaccination clinic on campus in partnership with Hamilton Public Health. All students, staff, visitors and faculty are welcome. No appointments are needed and first, second and third doses of the vaccine will be available. Walk-ins are welcome.
Date: Tuesday, January 18, 2022
Location: CIBC Hall, 3rd floor of the McMaster University Student Centre (MUSC)
Time: 9:30am to 3:15pm (closed for lunch 11:50am-1:00pm)
Please bring your OHIP and/or UHIP card with you to the clinic. International students, please bring physical, hard copies of previous vaccinations from other countries. McMaster participants must complete MacCheck screening before attending campus. Visitors must use the McMaster Safety App tool.
Appointments for COVID-19 boosters – and first and second doses of the vaccine – are also available locally and can be booked through regional public health agencies, and the City of Hamilton booking portal.
After January 18th, the McMaster Student Wellness Centre will be offering COVID-19 vaccination appointments to students. International students, please bring this completed form and your original vaccination documents with you to your appointment. Or, you can send the completed form and original vaccination documents to Hamilton Public Health.
Dawn Bowdish, an immunologist and professor in the Faculty of Health Sciences, offers her insights on the COVID-19 booster and how the third dose works to provide better protection.
Q: Does the booster help protect against the Omicron variant?
You need to get your third dose against Omicron. It’s a highly infectious variant that can sneak under the immune system of people who don’t have very, very high levels of antibodies. The best way to get those high levels of antibodies is to get that third dose. Although it won’t prevent you from getting infected completely, it’ll minimize symptoms and reduce the number of days that you’re contagious, thereby, infecting less people in your community. I also have a personal reason for wanting you to get vaccinated. I am desperate to get back to campus. I’d love to be having these conversations and to do my teaching in person. If we all get our third doses, it’ll help this pandemic minimize or end a little bit quicker and we’ll be able to get back to Mac which is where students and professors belong.
Q: Do I really need a booster if I am young, healthy and already have two doses?
You absolutely need to get your third shot, even if you’re young and healthy and you’ve had two doses. Most vaccines come in threes. If you cast back to any vaccines, you might have got as a young adult like Hepatitis B or HPV — and certainly all the vaccines you had as a child — they always come in a three-dose schedule. And that’s because the immune response is more programmed to forget things than it is to remember them. This protects us from having an immune response against everything we eat or breathe or touch. So, we really need three doses to sort of cement that immune memory and keep that with us. Now we may end up needing more doses in the future as immunity wanes and new variants emerge, but for now that third dose will help you have more minor symptoms should you get infected, and thereby prevent the risk of spread to your community.
Q: Does it matter what kind of booster shot I get?
You can mix and match your vaccine types. Currently, in Canada we’re saving the Pfizer vaccine for people who are under 30 and that’s because there’s a slight decreased risk of serious side effects in this age group. Moderna or Pfizer is being offered to everyone over 30 and you shouldn’t worry about mixing and matching your vaccine types. So, for example, if you got Moderna for your first two doses, and then you are offered Pfizer, it’s a great choice. All the vaccines offer really good protection. And there’s even some data suggesting that mixing and matching is even more protective than keeping the same dose over and over again. The best vaccine is the one that’s in your arm. Let’s all get vaccinated.
