Do boosters save people from getting very sick with Covid? New data from Britain say the opposite.

Newly mRNA boosted adults aged 40-74 are now TWICE as likely to be hospitalized for Covid as those who haven’t recently been boosted, a new British government report shows.

Vaccine advocates endlessly claim that though mRNA shots fail against Omicron infection in weeks, they still miraculously prevent Covid from becoming a serious illness that could require hospitalization.

These figures, which cover hospitalizations in June, suggest otherwise.

(See that blue bar? Those are the people who have had a booster within the last three months. That bar supposed to be lower than the other bars, not higher. Higher is bad.)



The data are buried on page 47 of the most recent Covid vaccine surveillance report, released Sept. 1 by the United Kingdom Health Security Agency. The British government checks hospitals for Covid patients and then compares them to its national immunization registry, providing comprehensive data on cases by vaccine status.

The report shows that in June, people aged 40 to 74 who had received an mRNA booster within the last three months had a 1-in-3,600 risk of being hospitalized with Covid. That figure was double the 1-in-7,200 risk for people who had received their last Covid jab more than six months ago. (It also shows that the jabs stopped working after three months for people 75 and older.)

The British government removed some raw data about Covid deaths and hospitalizations from the vaccine surveillance report months ago, when they began to show vaccines were not working well. Still, it remains a better source of information than anything the United States offers.

To explain the apparently negative effect of boosters, the report’s authors suggest that people 40 to 74 who received a third or fourth shot in the spring might be sicker than average Britons.

But they offer no evidence to support that theory.

Another possibility, of course, is that the antibodies that the vaccines cause people to make may actually somewhat worsen Omicron infections, a phenomenon known as antibody-dependent enhancement.

However, in people 75 and older, the boosters still seem to have some short-term protective effect – though another tricky epidemiological phenomenon known as healthy vaccine user bias means the benefit is probably much less than it appears.

The HSA survey also shows that almost everyone who is hospitalized with Covid in Britain has had at least two vaccine shots, including 87 percent of people 40-64 and close to 95 percent of those 65 and over.

The vast majority of those have had three shots.


Data this ugly could help explain why the White House is now proposing Americans get mRNA shots only once a year, a significant easing of previous pressure to get jabbed twice or even three times a year.

Of course, the fact that vaccine demand has collapsed completely and midterm elections are only two months away might also be playing a role.
