The four factors that increase the risk of getting infected with the coronavirus with the complete vaccination schedule

The vaccines they are the only ones protection tool against severe coronavirus disease. Almost no scientist or specialist thinks otherwise. However, there are a few risk factors to be taken into account for avoid infection with SARS-CoV-2even if you are fully vaccinated.

A UK government investigation, called the ‘COVID-19 Symptom Study’, concluded that the 0.2% of the population – 1 in 500 people – contract covid when they already have the complete vaccination schedule, that is to say the two doses of vaccine. Besides, they warned that four factors risk factors directly affect the possibility of contagion: vaccine type that the person received, the time elapsed since the completion of the immunization schedule, the immunological system and the variants In circulation.

Regarding the first point, the researchers pointed out that clinical trials have shown that not all vaccines have the same efficiency against the virus: Modern reduced the risk of becoming seriously ill with covid by 94%; the Pfizer by 95%; the AstraZeneca and the Johnson & johnson They have lower percentages of protection than the former, reducing the risk by around 66% and 70%. Meanwhile, the Sputnik V -developed by the Russian laboratory Gamaleya-, showed an efficiency of 91.6%; in Covishield -produced at the Serum Institute of India- it was 76% effective; the Sinopharm, 79.0%; and the CoronaVac (Sinovac), UN 50.7%. For this reason, many countries assess a third booster dose.

Meanwhile, the time elapsed since the person has finished their vaccination schedule it is also a point to be taken into account. We know that the protection of covid vaccines is not the same over the months (it starts to decrease after the sixth month), so many countries already apply a third dose in people at risk, especially in adult adults and people with comorbidities.

The Immune system every person is different and, for researchers, no less so in terms of exposure to the virus. The individual risk of a person will depend on their own immunity levels and other specific factors, such as your level of exposure to the virus.

The reality is that the immune system weakens with age, leaving the person more exposed to different Infectious diseases. This is why the elderly and those with co-morbidities were the first to be inoculated against covid in the world.

Their immune system is usually engaged, even when fully vaccinated, since vaccine protection decreases more rapidly than in the rest of the population. In addition, having been the first to be inoculated, the protection the serum breaks down.

Finally, the analysis, called “Study of COVID-19 Symptoms,” argues that the protection of the different vaccines is minor or major in front of the different mutation SARS-CoV-2. The researchers consider that different variations affected differently since the start of the pandemic. For this reason, for specialists, these have a lot to do with the increase in infections between inoculated and unvaccinated. The interesting variants do not affect the body in the same way as those of to worry, like the Delta, responsible for new infections among the unvaccinated, especially in the younger segment of the population.
