Research from Israeli Health Ministry’s Central Virology Laboratory, and Sheba Medical Center provides more information regarding Pfizer sustainability. They drew blood samples from 20 people who had the full dose 5 to 6 months previously. And compared them with a similar number who had a booster a month before. The result provides more evidence of a need for a Pfizer booster shot.
Aging Vaccinations Did Not Neutralize Omicron
‘People who received the second dose 5 or 6 months ago do not have any neutralization ability against the Omicron. While they do have some resistance against the Delta’ says director of Infectious Diseases Unit Prof Gili Regev-Yochay according to New York Post.
However, and this is positive news a Pfizer booster dose does reinstate resistance significantly. ‘People who have received the booster are better protected than those who received only the second. And of course, more than the unvaccinated,’ confirms Dr. Sharon Alroy-Preis, Israel’s health department’s head of public health services.
More Background to Evidence of a Need for Pfizer Booster
Times of Israel ran the story on December 12, 2021. They cite Prof Gili Regev-Yochay saying she was ‘very worried’ for people with aging Pfizer shots. However, on the positive side there is evidence a booster has ‘substantive resistance’ to Omicron. So what does this evidence of a need for a Pfizer booster tell us?
Well first of all this was a very small study of 40 people, so hardly statistically representative. Moreover, Prof Gili Regev-Yochay does not guarantee the booster will provide complete immunity.
However, on the positive side empirical evidence from early outbreaks suggest symptoms are generally milder. If we can no longer rely on Pfizer entirely. Then perhaps we are back to square one where the best protection is shielding ourselves?
