The scarcity of effective treatments and its virulence converted the vaccines into an essential tool to face it. The most used vaccines were the mRNA, adenovirus vector, and inactivated whole-virus. However, nowadays, infants aged<6months are not eligible for any vaccines against COVID-19, and...
SARS-CoV-2 has caused global waves of infection since December 2019 and continues to persist today. The emergence of SARS-CoV-2 variants with strong immune evasion capabilities has compromised the effectiveness of existing vaccines against breakthrough infections. Therefore, it is important to determin...
The first dose of COVID-19 vaccines led to an overall reduction in cardiovascular events, and in rare cases, cardiovascular complications. There is less information about the effect of second and booster doses on cardiovascular diseases. Using longitudinal health records from 45.7 million adults in...
The scientists note that it remains unclear if the greater antibody response generated by the Moderna vaccine translates into better real-world protection. But the study, they say, may help explain emerging differences in COVID-19 infection rates seen among re...
The researchers have concluded that the first COVID-19 drugs and vaccines should be tested on the rhesus macaques and not on other monkeys that are less vulnerable to the coronavirus disease.
community level, a kid who catches Covid-19 has the potential to spread that virus to the adults in their life who may not have gotten vaccinated yet. Some people can’t get vaccinated because of their immune systems or because they have a history of allergic reactions to vaccines, for ...
COVID-19 vaccines are saving an untold number of lives, but they can't stop the chaos when a hugely contagious new mutant bursts on the scene, leading people to wonder: Will we need boosters every few months? A new vaccine recipe? A new type of shot altogether?
DEAR MAYO CLINIC: I know COVID-19 has been around now for over a year, but I'm still confused by the different types of vaccines, including messenger RNA and vector vaccines. Can you explain how these vaccines work and the differences between these vaccines?
Moderna and BioNTech widely popularized mRNA vaccines by successfully commercializing the Covid-19 vaccine. She elaborated on programs for researchers to collaborate with multinational pharmas’ mRNA technologies at the R&D stage to sidestep the intellectual property (IP) waiver issue which some consider...
Although inactivated vaccines seem to have low efficacy to prevent Omicron infections among the population66,67, vaccination data were processed as a practical vaccination rate, based on the full vaccination rates and the efficacy of COVID-19 vaccines (see Supplementary Table 2). Please see ...
