A review of Johnson & Johnson’s COVID-19 adenovirus vector vaccine.

The verdict: The verdict (updated on August 24, 2021): Johnson & Johnson’s COVID-19 adenovirus vector vaccine was rather effective in phase-3 trials at preventing severe COVID-19. However, the real-life data show that the protection is short-lived, limited to 2 to 7 months after vaccination. The single-dose Johnson and Johnson vector vaccine creates the shortest period of protection. None of the intramuscular vaccines against COVID-19 limit transmission.
For the most vulnerable groups, in particular, people of advanced age who can not take other prevention, hygiene, prophylaxis, and early treatment measures, Astra-Zeneca-Oxford vector vaccine, two doses, may be a somewhat better option. Tens of thousands of people of advanced age vaccinated in Scotland apparently survived vaccination with Astra-Zeneca-Oxford. Adverse effects of Astra-Zeneca-Oxford vaccine are less pronounced than in younger groups. For younger people, and competent literate normal people of all ages, we do NOT recommend Astra-Zeneca-Oxford vaccine (as of August 2021).

The brainwashed masses are ready to inject themselves with anything. But will vaccines work in those who are in the high-risk group, that is, people aged 70 and older? It is unlikely. According to a 2006 study by Corsini et al., the currently available influenza vaccines do not work in 70% of those aged 70 to 80 do develop antibodies after a flu vaccination. Among those aged 80 and above, 90% do not develop antibodies after a flu vaccine administration.

COVID-19 vaccines are unlikely to protect those who are at a higher risk. A 2006 study: Vaccines fail to generate protective immunity in 50% to 90% of older individuals.

Seroconversion after a vaccine is 50% from 60 to 70 years old, 31% from 70 to 80 years old, and only 11% after the age of 80.
Conclusions: Billions are being spent on COVID-19 vaccines that are unlikely to work in the highest-risk group, those aged 70 and above.
