Increased Vaccine Supplies at Clinics for Week of July 19


COVID-19 Vaccine Clinic

  • York Region continues to make great gains in administering first and second COVID-19 doses with approximately 79% of those age 12+ with first doses and 60% aged 12+ fully vaccinated
  • York Region is receiving increased vaccine supplies next week; both Health Canada authorized mRNA vaccines (Pfizer and Moderna) will be available at all clinics as of Monday, July 19, 2021 as supply lasts
  • Both approved mRNA vaccines provide excellent protection against serious illness, hospitalization and death starting approximately 14 days following the first dos
  • Recently, the limited supply of Pfizer vaccines was temporarily reserved for youth ages 12 to 17 as the only approved vaccine available for this age group in Canada, but will now be available to all those age 12+ who live, work or go to school in York Region for first and second doses
  • As Ontario enters Step 3 with increased gathering limits and activities permitted, it is important individuals do not wait to get vaccinated
  • COVID-19 vaccinations have played a large role in the decreased case numbers, hospitalizations and deaths in recent weeks; in order to keep this trend continuing, we encourage all remaining residents who are unvaccinated to get both doses as soon as they can
  • Youth still have an opportunity to receive both doses before the start of in-person learning for the 2021/2022 school year
  • It remains critically important for all those who have not received a first dose to get one
  • While the first dose of the COVID-19 vaccine is very effective at preventing COVID-19 infection, serious illness, hospitalization and death about two weeks after receiving it, a second dose is still required to provide optimal and longer-lasting protection
  • Residents are encouraged to attend their second dose appointment or book an earlier appointment to complete the vaccine series and achieve the maximum level of protection from COVID-19 – particularly in light of the presence of the highly contagious Delta variant in our community
  • If the vaccine you received for your first dose is not available at your second dose appointment, it’s recommended you receive the mRNA vaccine available at that time; the National Advisory Committee on Immunization (NACI) considers both available mRNA vaccines to be interchangeable, if the same product is not readily available
  • The Ministry of Health reaffirmed this week that mixing of mRNA vaccines (Pfizer and Moderna), as well as mixing AstraZeneca and an mRNA vaccine, is safe, effective and enables more Ontarians to receive their second dose sooner
  • Ontario continues to follow the advice of the National Advisory Committee on Immunization (NACI) which recommends it is safe to mix these vaccines based on studies from the UK, Spain and Germany that found that mixing vaccines is safe and produces a strong immune response
  • Residents are reminded to follow safety protocols before and after receiving the vaccine, including social distancing, wearing a mask, washing your hands, monitoring your health and staying home if unwell
