The most common COVID-19 vaccines are produced by Pfizer and Moderna right now. Both are variations of an mRNA vaccine that has to be delivered in two separate doses to be fully effective.
But three weeks ago the UK announced that it would be spacing out the second dose by up to 12 weeks in order to give the first shot to more people. And there are now reports that the first dose could possibly be halved to make the available supply go further.
THE QUESTION
What happens if you can only get half the coronavirus vaccine due to a spread out delivery time or because someone halves the dose?
THE ANSWER
According to Dr. Kawsar Talaat, an infectious disease expert and vaccine researcher at Johns Hopkins, there’s little risk in “waiting too long,” because the first dose of the vaccine causes the body to start building immunity.
The Centers for Disease Control and Prevention recommends that the second dose of vaccines be administered within three weeks to one month, but stated that “there is no maximum interval between the first and second doses for either vaccine.” #WakeUpCLT #COVID19
