Can I Get COVID-19 Again?
Getting Covid-19 again seems to be rare but you have a still possible to get Covid-19 again after the recovery of it.
It is called reinfection. According to the knowledge from similar viruses, reinfections are expected.
This situation is also valid for vaccinated people. If you got the shot of Covid Vaccine and still virus can infect you again and thanks to the vaccine, the risk of severe illness and death decrease significantly.
There is a study called SARS-CoV-2 Immunity and Reinfection Evaluation (SIREN) which was conducted by the Department of Health and Social Care and Public Health in England. The study showed that the possibility of reinfection is decreased by 83% for at least five months due to the responses of the immune from the previous infection.
The results from the same study suggested that cases of reinfection are rare and the ratio of occurrence is fewer than 1% of about 6.600 participants who had already been infected by the COVID-19 virus.
Reinfection is a rare situation but it is significant to take precautions such as wearing masks, handwashing, and social distancing.

The pandemic of Covid-19 continues to affect our lives and thankfully vaccines are coming with hope to fight this pandemic. However, new versions of the Covid-19 virus are reported and put us in a stressful place again.
Let’s see what is the variant Of Covid-19 and how does it affect us?
The mutation is responsible for the formation of new variants of the virus and some of these variants continue to spread and some of them are disappeared.
As we know, new variants of Covid-19 are reported. One of them is detected in the UK and called B.1.1.7. It is more contagious when compared to their variants.
Last October, in South Africa, named with B.1.351 variant was determined and lastly, P.1 variant was detected passenger from Brasil at the airport in Japan.

What about the Vaccines?
Current vaccines were based on the previous version of the virus. However, scientists believe that they would be effective for new types of viruses.
The first result of BioNTech/Pfizer vaccines provides protection but less effective to new variants.
Two new vaccines (from Novavax and Jannsen) to be approved sooner would provide the protection as well. Experts from Oxford-AstraZeneca explained that their vaccine is protective against to new English variant.
Experts state that although this vaccine still provides protection against severe Covid-19 diseases, it is less effective against the South African variant.
Preliminary results from Moderna also show that the vaccine is effective against the South African variant. However, experts point out that the immune response may not be strong and long-lasting in this variant.
Experts say that many different variants may emerge in the future, but even in the worst-case scenario, vaccines can be redesigned or modified within a few weeks or months.
It is stated that the flu vaccine is updated to cover new strains every year, as well as the coronavirus vaccines, can be renewed.
