After administration, COVID-19 vaccines launch a chain of immune reactions involving B cells [6]. They cause an antibody response, with antibodies binding to the spike protein to prevent SARS-CoV-2 from entering the cell [6]. The immunological memory created by the COVID-19 vaccines is the...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly spread around the globe leading to the COVID-19 pandemic. To mitigate the effects of the virus on public health and the global economy, vaccines were rapidly developed. In less than one year, with respect to usual ...
China's renowned respiratory-disease expert Zhong Nanshan said Sunday that the mass inoculation of homegrown COVID-19 vaccines underway in China shows the vaccines are safe and effective. The two vaccines currently in use in China, the China National Biotec Group (CNBG) COVID-19 vaccine and the...

China always puts vaccine safety, efficacy first: spokesperson China always puts the safety and efficacy of COVID-19 vaccines first, a spokesperson for the fourth session of the 13th National Committee of the Chinese People's Political Consultative Conference said on Wednesday. Web Editor:MXJ...
Most people who get COVID-19 are unvaccinated. However, since vaccines are not 100% effective at preventing infection, some people who are fully vaccinated will still get COVID-19. An infection of a fully vaccinated person is referred to as a “breakthrough infection.” ...
Several COVID-19 vaccines have shown good efficacy in clinical trials, but there remains uncertainty about the efficacy of vaccines against different variants. Here, we investigate the efficacy of ChAdOx1 nCoV-19 (AZD1222) against symptomatic COVID-19 in a post-hoc exploratory analysis of a Phas...
The initial model used by the researchers was based on the original strain of COVID-19. In future research, they hope to be able to apply the model to new variants and potential new vaccines. "Overcoming this challenge (of variable effectiveness of vaccines across individuals) would allow pred...
Severe acute respiratory syndrome coronavirus 2 had devastating consequences for human health. Despite the introduction of several vaccines, COVID-19 continues to pose a serious health risk due to emerging variants of concern. DNA vaccines gained importa
Domestic drugmaker Sinopharm's two vaccines are both more than 70 percent effective against symptomatic cases of COVID-19, according to a study published on Wednesday on the world's first third-stage clinical trial of inactivated vaccines. ...
