Tests have already shown that coronavirus protection decreases after a certain period of time. Out of concern about the aggressive delta variant and a fourth wave in the fall, a third corona vaccination is now to be given. According to the Israeli health authority, Biontech only provides 64% protection against the more dangerous Delta variant. A third campaign is already underway there to refresh vaccination protection for older people.
8 signs that you have already had corona
Older and frail people should be vaccinated a third time
It is obvious that the elderly and people in need of care in particular, as well as people with immunodeficiency and immunosuppression, should be protected by a third booster vaccination. This should take place after six months at the earliest with Biontech and Moderna. This is the period during which a reduction in vaccination protection has been observed in some people. The third campaign is scheduled to start in September and will primarily be carried out by mobile care teams. The vaccine must reach people who are no longer mobile themselves. Otherwise, there are fears of a wave of infection in the fall/winter of this year, especially in retirement and nursing homes.

Further vaccination also with Johnson & Johnson and AstraZeneca
Not only the vaccinations with Biotech/Pfizer and Moderna will be boostered, people who have received a vaccination with Johnson & Johnson and AstraZeneca should also receive a booster vaccination after six months. According to studies from Israel, the Johnson & Johnson vaccine is said to last eight months, but its effectiveness against the delta variant is said to be lower than that of mRNA vaccines.
How well and for how long do the vaccines protect
As previously mentioned, a decrease in vaccine protection was observed after six to eight months. According to Dr. Andreas Radbruch, immunologist and scientific director of the German Rheumatism Research Center Berlin, both the primary and secondary vaccines should provide good efficacy against all known mutants. In a recently published study, US researchers said that people who have developed antibodies against the virus due to a coronavirus infection are likely to be protected against Covid-19 for years. However, according to current knowledge, this should also be refreshed at the intervals mentioned above.
