LONDON, ONT. -- CTVNewsLondon.ca has everything you need to know about receiving the vaccines in London, Ont., including locations, how to register, and who is next in line.

WHO CAN GET VACCINATED RIGHT NOW?

Anyone 12 and older.

Some area pharmacies and doctor's officers were providing the AstraZeneca vaccine to all adults over 40, however the province announced on May 11 that it would no longer be offering the first dose of the AstraZeneca vaccine due to an increase in reports of rare blood clots.

Second doses of AstraZeneca are available for those who did get AstraZeneca as their first dose, though they can also choose one of the mRNA vaccines for their second dose if they prefer. Pharmacies and doctor's offices are now offering mRNA vaccines as well as the Middlesex-London Health Unit.

WHO IS NEXT IN LINE?

The second phase, or the mass vaccine rollout, is underway, with the vast majority of the adult population and youth ages 12 to 17 all now eligible. Trials are underway on the use of the vaccine on children under the age of 12.

HOW WILL I FIND OUT WHEN I CAN RECEIVE THE VACCINE?

The Middlesex-London Health Unit is communicating details regarding first and second-dose vaccinations for the public through multiple channels including online and through social media.

WHERE DO I SIGN UP?

Those who are eligible can book an appointment at: https://www.covidvaccinelm.ca/

Appointments to receive the vaccine at a local doctor's office or pharmacy are made directly with the location involved. The full list of participating pharmacies as well as contact information is available here.

WHAT DO I NEED TO KNOW BEFORE REGISTERING?
