The vaccine from Johnson & Johnson only needs to be vaccinated once and has been shown to be highly effective in studies.

In very rare cases, however, the administration led to blood clots.

The vaccine from US manufacturer Johnson & Johnson, also known as Ad26.COV2.S, has also been vaccinated in Germany since the beginning of May. In the USA, however, there was a vaccination freeze with the vaccine at the beginning of April.

This was due to six cases of cerebral vein thrombosis that occurred after vaccination

. The temporary suspension, which the American authorities had decided on, lasted around ten days. The suspension was recommended out of "excessive caution", the medical journal quoted the health authority CDC and the drug authority FDA.

This case is reminiscent of the approach taken by the German Federal Ministry of Health in the case of the Astrazeneca vaccine.

Here, too, a connection was established between vaccination and the development of thrombosis, especially for those under 60 years of age.

As a result, there was a brief vaccination freeze in March.

Both cases - the Astrazeneca and Johnson & Johnson supplements - are vector vaccines.

Both preparations are being reinstated as the relevant authorities have concluded that the benefits of vaccination outweigh the risks.

Corona vaccination from Johnson & Johnson: Proven effectiveness

In fact, a recent study published in the "

New England Journal of Medicine

published",

the Johnson & Johnson vaccine effective only seven days after vaccination to be effective against heavy critical / Covid-19

. In addition, it apparently also prevents symptomatic infections with the variants that predominate in South Africa and Brazil, informs the Deutsche Apotheker Zeitung (DAZ). For the evaluation, it was observed from September 2020 to January 2021 how the Johnson & Johnson vaccination affects the corona risk. For this purpose, the researchers randomly assigned 44,325 adult participants in a 1: 1 ratio to a single dose of Ad26.COV2.S (5 × 10 10 virus particles) or placebo. 34 percent of the participants were over 60 years old, quotes the Deutsche Apotheker Zeitung.

The study showed that the vaccination showed an effectiveness of 77 percent against severe Covid after around two weeks.

After 28 days, people were even 85 percent protected

from developing critical corona courses

.

In addition, the effectiveness continued to increase for about eight weeks after the vaccination, according to the DAZ.

There is also no evidence that the protection decreases over time.

Possible side effects of the Johnson & Johnson vaccination

The registration study for the Johnson & Johnson vaccine tested, among other things, which side effects the vaccination can lead to. The

Gesundheitinformation.de

portal

, which is commissioned by the Institute for Quality and Efficiency in Health Care (IQWiG), informs that the vaccine was tested on around 44,000 participants in the approval study.

In addition to slight and temporary vaccination reactions such as pain at the injection site, the study directors could not observe any serious side effects in the participants, it says.

However, very rare side effects usually cannot be detected during the approval studies of a vaccine, according to

Gesundheitsinformation.de

.

Therefore, after vaccines are approved, international authorities would always monitor reports of suspected adverse reactions.

 This is how the six cases of cerebral vein thrombosis in the USA after the Johnson & Johnson vaccination became known

.

These complications have so far been very rare, but vaccinated people should act immediately if they suspect a thrombosis.
