Most vaccines, other than mRNAs, probably do not prevent Omicron


We are talking about vaccines such as AstraZeneca, Johnson & Johnson, the Chinese vaccines Sinopharm and Sinovac and the Russian Sputnik.

All vaccines, especially mRNAs, seem to provide a significant degree of protection against the heavy disease, της hospitalization and his risk of death due to Covid-19 disease caused by the new Omicron variant of the coronavirus.

However, only mRNA vaccines (Pfizer / BioNTech and Moderna), mainly after Tuesday dose, seem to be successful in prevent virus infection and simple infection, as reported by the first relevant studies. And unfortunately these more advanced vaccines are not available in most of the world, but mainly only in developed countries.

Preliminary research data show that non-mRNA Covid-19 vaccines and used in many countries offer almost no protection against someone being infected with Omicron.

The above data, according to the “New York Times”, refer to vaccines such as AstraZeneca, Johnson & Johnson, the Chinese vaccines Sinopharm and Sinovac and Russian Sputnik, which provide more or less protection against serious disease, but do very few things to stop the spread of Omicron. Because many countries, especially developing countries, have based their vaccination programs on such non-mRNA vaccines, this can have serious implications for the pandemic 2022.

A global outbreak of infection in a world where there are still billions of unvaccinated people not only threatens the health of vulnerable people but also increases the risk of new, worse coronavirus variants emerging.

Most data – so far – are based on laboratory studies and not on clinical data, so they fail to take into account the full range of immune response. Nevertheless, they provide a first impression.
