Why do we need COVID vaccine boosters for the Omicron variant?
I have seen a few comments about the need for COVID-19 vaccine boosters before and after the appearance of the new Omicron variant. Of course, anti-vaxxers use this as a reason to deny the effectiveness of the vaccine. However, I’ve even seen pro-vaxxers misunderstand why boosters are needed.
Today, Pfizer announced that its preliminary studies showed that individuals who have received boosters produce about 25X more neutralizing antibodies against the Omicron variant than those who received the COVID-19 vaccine alone. This is awesome news with the caveat that this has not been peer-reviewed or published, it is just a report from Pfizer itself. In the hierarchy of vaccine research, it is pretty low until it is published in a medical journal.
I’m going to try to explain the reasoning behind the need for COVID-19 vaccine boosters against the Omicron variant. I hope it provides some science-based facts about boosters so that it might help you in discussions about the vaccine and new variant. I’m dividing my explanation into three broad areas, with the intent to make the science as clear as I can.
And just to remind everyone, I am fully boosted with the Moderna vaccine.Read More »Why do we need COVID vaccine boosters for the Omicron variant?
