Protection against infection from a fourth Pfizer vaccine dose wanes to zero in just eight weeks, an Israeli study published in the NEJM has found.

Prof Yaakov Jerris, the Director of a Covid ward in an Israeli hospital, has said between 70% and 80% of the serious cases in his hospital are vaccinated and the vaccine has "no significance regarding severe illness".

Covid ICU admissions in Israel have hit record levels, reaching 130.5 per million on January 26th, topping 127.1 on January 19th 2021. Why is this when Omicron is milder and the country is now highly vaccinated?

Unadjusted vaccine effectiveness against infection is negative against Omicron for the triple-jabbed over-30s, new UKHSA data show, meaning infection rates per 100,000 are higher in the triple vaccinated.

A fourth dose of Covid mRNA vaccine is not effective against Omicron infection, preliminary research from Israel has shown – as the Omicron surge hits ICUs.

The UKHSA vaccine report this week shows a striking drop in effectiveness against hospitalisation and a further fall against infection during the Omicron surge. What's going on?

The coronavirus is "nowhere near" endemic, the World Health Organisation has said, while Pfizer's CEO says an Omicron vaccine is on its way and admits two doses no longer work. Some people don't want this to end.

Covid should be treated as an endemic virus similar to flu, and ministers should end mass-vaccination after the current booster campaign, Dr. Clive Dix the former Chairman of the U.K.’s vaccine taskforce has said.

Omicron bites hard in the UKHSA vaccine report this week as unadjusted vaccine effectiveness against infection (calculated from the raw data) plummets across all age groups, hitting a new low of minus-151%.

Professor Andrew Pollard, the head of Britain's vaccine body, has said fourth jabs should not be offered until there is more evidence as he warned that giving a new dose to people every six months was “not sustainable”.
