Covid-19 Updates in Brief, Part # 18
Covid updates 18 reveals that Covid-19 cases decreased in many parts of our world . Researchers and scientists have developed Covid-19 vaccines. These vaccines are the only known reliable source to protect from Covid-19. Unfortunately, these vaccine do have some side effects. Some side effects of these vaccines appear after 6 months of vaccination. Scientists and researchers are trying their best to eliminate such side effects. This is a tedious job and need patience and a vast knowledge. It might take a long time to develop a 100 % safe vaccine for human.
At the moment, scientists are focusing full attention to improve the present Covid-19 vaccines. That’s why other Covid-19 updates are very rare to publish. Moreover , researchers/scientists have gained enough knowledge about Covid, and there is very little more to discover. You must have noticed that Covid-19 updates in brief ‘s volume is becoming less and less every fortnightly. Reason behind it is that researchers have to wait for a long time for clinical results of vaccination. This period can be years long.

mRNA Covid-19 vaccines and heart inflation.
A meta analysis published in ” The Lancet Respiratory Medicine ” shows the following results:
- Present studies concluded that Covid-19 vaccines may increase the risk of heart inflammation . It could be a danger.
- A combined analysis from previous 22 studies shows that , heart inflammation risk after a Covid-19 vaccine is similar to that following vaccination against other diseases.
- Male and people under the age of 30 years, were at a higher risk of heart inflammation. Especially after the 2nd dose.
- Above data shows that risk of heart inflammation after having Covid-19 vaccine is low.
New Covid vaccine booster.
- The drug maker Moderna announced on April 19, 2022 that their updated mRNA Covid-19 booster has shown better protection against several SARS-CoV-2 variant including Omicron.
- The booster was designed to target two variants, the original variant and the Beta variant. The vaccine is also more effective against the original, Beta and Omicron variant, 6 months after administration.
- The new booster is called 1273.211.
BA.2.12.1. A new sub variant of Omicron.
- BA.2.12.1. a new sub variant of of BA.2 sub variant of Omicron is spreading rapidly in the U.S.A. and overtaking the BA.2 Omicron sub variant.
- Up till now, very little is known about this sub variant. However it appears it will be highly transmissible .

mRNA Covid-19 vaccine and heart inflammation.
It was observed in several studies that risk of heart inflammation after mRNA Covid-19 vaccination is real , but fairly mild and extremely rare.
- Many studies show that adolescents and young males have a higher risk , especially after 2nd dose.
