Scientists have proven that vaccines protect against long-term covid

(ORDO NEWS) — The vaccines appear to significantly reduce the risk of longcovid, UK health officials say. In recent studies, they found that people who were vaccinated against covid were significantly less likely to develop long-term symptoms than those who were not vaccinated.

The UK Health Safety Agency reviewed 15 studies conducted in the UK and other countries up to January 2022, which examined various aspects of the relationship between vaccination and long-term covid symptoms. Eight of these studies attempted to measure the impact of vaccination prior to exposure.

Covid-19 vaccines still provide some degree of protection against the coronavirus, although that effectiveness is declining over time and with the introduction of varieties such as omicron. But even vaccinated people who got sick, the review found, were still less likely to report lingering symptoms.

In particular, the researchers calculated that vaccinated people who contracted COVID-19 were more than half as likely to report symptoms after more than 28 days as unvaccinated people.

This group included people who received two doses of the mRNA vaccine or the AstraZeneca vaccine, as well as people who received one dose of the Johnson & Johnson vaccine. The protective effect of long covid vaccines was greatest for people over 60 and least for people aged 19 to 38.

All of these studies were observational, meaning they can only show a correlation between two things, so further research is needed, the doctors said.
