Why is there no vaccine for norovirus as it spreads across the US? How long do you have to wait?
Norovirus Vaccine: Currently, there is no vaccine for norovirus because of the many strains and the elusive nature of how the virus evolves. According to research, many studies and pharmaceutical companies are trying ways to make norovirus vaccine. However, it may take years for a vaccine to be approved for the public even after trials are completed. In the meantime, read on to learn some ways to protect yourself from norovirus.
More than 20 million cases of norovirus are reported each year across the United States.
norovirus vaccine, In recent weeks, norovirus outbreaks have been reported at high rates across the United States. According to experts, more and more people are suffering from vomiting, diarrhea and other potentially dangerous symptoms associated with the virus – and so, the question remains why there is still no vaccine to protect against these common infections.
The Centers for Disease Control and Prevention, or CDC, has confirmed nearly 100 norovirus cases since December last year, a significant increase from the same time in 2023. Recently, the Food and Drug Administration also issued a warning to consumers that oysters and clams will. Contaminated with norovirus – This is an example of how the virus is spreading.
An average of more than 20 million cases of norovirus are reported each year across the United States, leading to more than 100,000 hospitalizations — mostly older adults and children with severe symptoms. It has also been estimated that this virus causes losses of US$2 billion annually.
However, there are some preventive tools available to stop transmission and prevent severe disease but there is no vaccine yet. According to experts, many well-known pharmaceutical companies are working on norovirus vaccine but there is no news of the availability of the vaccine in the near future.
Why is there no vaccine for norovirus yet?,
According to doctors, norovirus is a highly infectious and dynamic target virus with complex genetic evolution that has and will continue to arise in different forms.
And because it evolves rapidly, creating a vaccine is a major hurdle.
Additionally, there are different subtypes of norovirus that frequently cause outbreaks – which is why most people have repeated infections throughout their lives. Therefore, it is never possible to develop immunity against one strain of norovirus.
vaccines are being made
Faced with challenges, researchers say they are working on vaccines – trying to create the perfect vaccine to help prevent and treat the condition.
Several experimental vaccines are being tested and investigated, including the 2023 shot created by researchers at Washington University School of Medicine in St. Louis, which adds norovirus to an existing vaccine for rotavirus, another pathogen that causes diarrhea. Additionally, many pharmaceutical companies are trying to develop vaccines, many of which are currently in clinical trials.
Health.com says one of the most promising is Moderna’s vaccine candidate — which is currently being tested on human participants.
How can you prevent norovirus without the vaccine?
According to doctors, norovirus is highly contagious and once you fall ill, it can be difficult to stop. This is related to the structure of the virus itself. And so, it is important to protect yourself from it.
Be sure to keep healthy hygiene habits. Always wash your hands before eating and after going to the toilet. Also, cook shellfish thoroughly, wash your produce before eating, clean any contaminated surfaces and wash your clothes in hot water to reduce your chances of getting sick.
