Many vaccines are needed to prevent Covid-19 4

A study conducted by the world's leading experts said that to repel Covid-19, a global strategy and many vaccines are needed.

The study, with the participation of Director of the US National Institute of Allergy and Infectious Diseases Anthony Fauci, was published in Science magazine on May 11.

Scientists have raised challenges in the preparation process and warned that just one vaccine is not enough to prevent the Covid-19 pandemic.

`The needs of the entire world and the differences in pathogens, depending on geographical location, require more than one effective vaccine,` the study writes, emphasizing the importance of coordinated implementation of the strategy.

`While much of the research is focused on trials in the US, the Covid-19 Prevention Network is coordinating with the World Health Organization (WHO) and the Coalition for Epidemic Preparedness Innovations (CEPI) as well as other

Scientists say more than one vaccine is needed to control Covid-19.

The study confirms that there are still too many unknowns related to Covid-19.

`The current top goal is safety, but in theory, vaccines have the risk of causing symptoms of nCoV to become severe,` the work states.

Another issue raised is the effectiveness of the vaccine for each age group (both the elderly and adolescents) as well as the mutations of the virus.

Regarding the idea of ​​proactively infecting volunteers with nCoV to speed up the development process, the study emphasizes the need to be extremely cautious, warning that there is currently no drug to treat if Covid-19 patients experience complications.

`Whether such trials are worthwhile or time-saving, clinical studies as well as review by ethical expert panels and vaccine developers are needed,` the study wrote.

Since the outbreak, more than 100 vaccine `candidates` have been registered with WHO.

Last month, WHO also launched a global campaign called Solidarity to accelerate the process of developing safe and effective vaccines and treatments.
