the Johnson & Johnson vaccine remains waiting while experts assess the potential risk of rare blood clots
the temporary maintenance on the Johnson & Johnson vaccine is expected to continue for at least another week while CDC advisers continue to analyze data on unusual blood clots possibly related to the injection. If the vaccine is determined to pose a risk, regulators can issue updated information on who should and should not receive it. Some fear the break will be fuel for disinformation and conspiracy theories, and devastate public confidence in the vaccine. But there is also the possibility that the decision to take a break reassure the Americans that the FDA takes all health problems, no matter how rare or unlikely, seriously.
It is important to note that the risks, if any, are extremely low“About one in a million. The government says there is no evidence of similar clots after vaccination with the injections of Pfizer and Moderna.
Pfizer CEO anticipates need for revaccinations
In regards to coronavirus variants rise, drug makers and the U.S. government are prepare for the possibility that a third injection may be needed nine to 12 months after the initial vaccination. Albert Bourla, CEO of Pfizer, said it is “likely” that individuals need a booster and possibly revaccination every year thereafter, just like the flu shot. David Kessler, the scientific lead for the Biden administration’s Covid response, also noted that additional shots may be needed at a congressional committee meeting this week. So far, data has shown that the Pfizer vaccine is effective against the South African variant, B.1.351, for at least six months. Moderna hopes to have booster shots for her two-dose vaccine available in the fall.
Variants are fueling new coronavirus outbreaks, but experts remain optimistic about vaccines
The three most notable variants of Covid-19 – which were first recorded in Brazil, the UK and South Africa – have spread to other countries. Strain B.1.1.7, for example, is now the main source of new infections in the USA. However, scientists stay optimistic that public health measures such as social distancing and mask wearing may continue to fight these new variants. After a deadly outbreak in the UK, cases of B.1.1.7 have now slowed considerably thanks to strict lockdown and vaccinations.
All of the major vaccines used have been shown to be effective against variants of Covid-19. “Breakthrough infections” – when a vaccinated person still gets sick – are possible but very rare. These infections also tend to fewer symptoms and are less transmissible. Vaccine producers are working on vaccines that will target variants more directly, but in the meantime, current vaccines should keep most people from getting seriously ill.

A question
Are there other variants of Covid-19 that we should be worried about?
The CDC is currently monitoring other variants. While there are others, and new ones could develop at any time, there is currently no variant of SARS-CoV-2 that is “high consequence,” a classification by the CDC for them. variants that have been shown to be resistant to preventive or medical measures. It is also important to note that not all genetic changes in the virus are necessarily dangerous, and many have already been hypnotized careful and exhaustive studies show that there are real reasons to be alarmed.
