WHY UNVACCINATED HAVE BETTER IMMUNITY AND RESSITANCE AGAINST OMICRON?
Redaktionsnetzwerk Deutschland –
Booster vaccinations in NRW are now possible after four weeks
- Booster vaccinations are possible earlier in North Rhine-Westphalia as the first federal state.
- Citizens can get a booster vaccination after just four weeks.
- The reason for this is that many people have recently been turned away because the second vaccination was less than five months ago.
In North Rhine-Westphalia, the booster vaccinations are now possible much earlier. Citizens can get the booster just four weeks after the second vaccination, reports the “Siegener Zeitung”, a partner of the RedaktionsNetzwerk Deutschland (RND) . Previously, this period was five months.
A corresponding decree had gone to all circles, a spokeswoman for the health ministry confirmed to the newspaper. The aim of the decree is that nobody is sent away from the vaccination center just because less than five months have passed since the second vaccination…Read More
Vaccines induce lower levels of neutralising antibodies against omicron, boosters improve levels: study
Medical Xpress – Researchers from the University of Oxford have analyzed the impact of the omicron COVID-19 variant of concern on one of the immune responses generated by vaccination.
Using blood samples from individuals who had previously received two doses of the Oxford-AstraZeneca or Pfizer-BioNTech vaccines as part of the Com-COV study, and a live virus isolate, they demonstrate substantial decrease in neutralizing titres—a measure of the level of neutralizing antibodies generated in responses to vaccination against, or infection from, COVID-19.
The results, published on the pre-print server MedRxiv, indicate that the omicron variant has the potential to drive a further wave of infections, including among those already vaccinated, although the researchers highlight that there is currently no evidence of increased potential to cause severe disease, hospitalisations or deaths in vaccinated populations.
These results align with recently published data from UK Health Security Agency, showing reduced effectiveness of two doses of these vaccines against symptomatic disease due to the omicron variant compared to delta. Importantly, this effectiveness was improved by a third dose of vaccine. Read more
