Researchers from Umea University, in a fresh study explored the efficacy of the COVID-19 Vaccines long-term.

The scientists disclosed they learned that while protection from the damaging virus may start to wane at around seven months post-vaccination, the shot was effective at protecting consumers from serious infection, agency report stated.

Researcher Peter Nordstr枚m said: 鈥淭he bad news is that the protection against infection seems to be diminished by seven months after the second dose of the vaccine.

鈥淭he good news, however, is that the protection against severe infection that leads to hospitalisation or death seems to be better maintained.

Vaccination is therefore very wise and important.鈥�

In exploring the prevention of serious infection for the study, the researchers analysed data from people enrolled in the Public Health Agency of Sweden.

The experts examined those who had received the Pfizer, Moderna, and AstraZeneca COVID-19 Vaccines, and compared their infection status up to nine months after full vaccinations with those who had not been vaccinated against COVID-19.

In a second analysis, the researchers evaluated the severity of COVID-19 infections related to vaccination status.

Overall, the study indicated that protection against COVID-19 got weaker over time. However, it varied with each vaccine type. Six months after the second dose of Moderna, participants were roughly 60 percent protected from infection; they were nearly 30% protected six months after the second dose of Pfizer.

According to them, more importantly is the fact that the vaccines proved to be more effective at preventing severe cases of COVID-19.

Participants were nearly 90 percent less likely to contract severe cases of COVID-19 within one month of vaccination, and nearly 65 percent less likely to develop a severe infection between four and nine months post-vaccination.

The researchers also learned that older consumers may be more vulnerable to infection, regardless of what type of vaccination they received or how much time had passed since vaccination.

Marcel Ballin, one of the researchers, also said: 鈥淭he results underscore and support the decision to offer a third dose.

鈥淚n particular, the results show that it was correct to prioritise the oldest and frailest individuals.鈥�

Going forward, the researchers have noted they hope their findings will influence public health strategies regarding the booster shot 鈥揺specially for those who have the highest risk of contracting COVID-19 in countries across the world.
