Countries all over the world are launching the SARS-CoV-2 (CCP virus)  vaccine, but its effectiveness and safety have been questioned. According to media reports, there have been cases of medical staff becoming infected after being vaccinated in both the United States and Spain.

Matthew W., an emergency room nurse in San Diego, California, was vaccinated on December 18 with a vaccine jointly developed by the US pharmaceutical company Pfizer and German BioNTech. However, six days later, on December 24, symptoms such as chills began to appear. Later, he fell due to muscle aches and fatigue. He was diagnosed by the hospital on December 26th.

In addition, a nurse who works in a nursing home in Lleida, Catalonia, Spain, tested positive 24 hours after being vaccinated with Pfizer/BioNTech vaccine on December 27. The health department subsequently confirmed the matter.

Some experts say that the confirmed doctor may have been infected before the vaccine. Pfizer previously stated that the vaccine needs to be vaccinated in two separate doses, 3 weeks apart, and the best protective effect can be achieved 7 days after the second dose. The effective rate can reach 90%.

For the CCP, Sinopharm claimed that its vaccine has an effective rate of 79%. However, internal news spread on the Internet that its vaccine is only 60% effective against the original strain, not to mention the various mutant strains currently circulating. Radio Free Asia confirmed that at least hundreds of foreign workers from state-owned enterprises who were vaccinated in China were infected collectively abroad.

SARS-CoV-2 is very easy to mutate, and its mutation rate is much higher than that of vaccine development, so it is difficult to develop an effective vaccine. After the outbreak at the beginning of this year, many studies have shown that some people infected with the CCP virus do not produce antibodies. Even if antibodies are produced, their effectiveness can generally only last for two to three months.

However, after countries scrambled to compress the R&D process to push the vaccine, the above-mentioned doubts rarely appeared in the media.
