JERUSALEM (Reuters) -The coronavirus variant discovered in South Africa may evade the protection provided by Pfizer/BioNTech's COVID-19 vaccine to some extent, a real-world data study in Israel found, though its prevalence in the country is very low and the research has not been peer reviewed.
The study, released on Saturday, compared almost 400 people who had tested positive for COVID-19, 14 days or more after they received one or two doses of the vaccine, against the same number of unvaccinated patients with the disease.
It matched age and gender, among other characteristics.
The South African variant, B.1.351, was found to make up about 1% of all COVID-19 cases across all the people studied, according to the study by Tel Aviv University and Israel's largest healthcare provider, Clalit.
But among patients who had received two doses of the vaccine, the variant's prevalence rate was eight times higher than those unvaccinated - 5.4% versus 0.7%.
This suggests the vaccine is less effective against the South African variant, compared with the original coronavirus and a variant first identified in Britain that has come to comprise nearly all COVID-19 cases in Israel, the researchers said.
"We found a disproportionately higher rate of the South African variant among people vaccinated with a second dose, compared to the unvaccinated group. This means that the South African variant is able, to some extent, to break through the vaccine's protection," said Tel Aviv University's Adi Stern.
The researchers cautioned, though, that the study only had a small sample size of people infected with the South African variant because of its rarity in Israel.
They also said the research was not intended to deduce overall vaccine effectiveness against any variant, since it only looked at people who had already tested positive

Thanks for giving me, one of my really rare headaches and on a Sunday.
That, post is why I hated statistics at all levels.
Monkeys may fly out of my butt.
HAHAHA!!
My thought as well.
Also, it seems to hit some racial/ethnic communities harder than others.
If true, then there is no reason to take the “vaccine” (which is not really a vaccine)
Ping to post13.
Which is part of the reason I have not received a vaccine yet.
Not sure it will work
Yes, it's interesting overweight people with high blood pressure, and vitamin D deficiencies who FLY don't seem to have the same high rates of covid that overweight people with high blood pressure, and vitamin D deficiencies THAT DON'T FLY seem to have ... Might be the first description applies primarily to blacks and the 'who fly' part to primarily whites. This feels of bio-weapon...
Be sure to have plenty of vitamins A, Bcomplex, C, D3, K2 plus iodine, zinc, quercetin, l-lysine, xclear, natural antibiotics.
One of the key take away should be that every one of the positives was before the 14 day full antibodies titer was reached.
Here is a study with extensive antibodies titier work look at figure 2D specifically the B1.351 strain the data in review is the pink dots. This group also ran analytics for T cells as well the paper is a good read if you can understand the underlying science. After 14 plus Pfizer dose two both antibodies and T cells are active against the B1.351 strain at levels that are comparable to the natural response levels of someone who survived the SA strain. What is also evident is the other strains the vaccine creates antibodies at a level up to 12 times the survival level immune response. But don’t take my word for it the science is here to read.
