A warning about why it’s too soon to mandate 3rd doses of coronavirus vaccines

Reuters reports a study from American researchers that found that in 32 fully vaccinated individuals, a 3rd dose of an mRNA vaccine did boost antibody levels, the antibodies that this 3rd dose provoked were not any better at fighting off more dangerous coronavirus variants.

Now a study result like this doesn’t mean that a 3rd vaccine dose is the wrong strategy to pursue in people with immune deficiencies or in seniors who have lowered immunity in general.

But before authorities mandate the use of 3rd vaccine doses in the general public, it’s very important for a randomized trial to show that this will strategy will actually make a difference and not just use up precious stocks of vaccines.
