All medical interventions lug risks and benefits. Scientists from vxcialistoufjg.com’s facility for Vaccine development and accessibility apply insights from rotavirus come COVID-19.

You are watching: Benefits of vaccines outweigh the risks

With every the monitoring coming in, an additional observation came to be clear: rotavirus vaccines work very well.

Countries that have introduced rotavirus vaccines have actually seen swift and far-ranging reductions in rotavirus hospitalizations—a median reduction of 59 percent—in youngsters under 5 years of age. Given the overwhelming evidence in favor of the vaccines, the civilization Health organization recommended in 2009 the rotavirus vaccines be contained in all national immunization programs for infants.

In the te since, much more than 100 nations have added rotavirus vaccines right into routine immunization. Real-world vaccine effectiveness has ranged indigenous 45 to 90 percent. Researchers have ongoing to monitor intussusception over the years and also maintain the reference that the vaccines’ benefits heavily outweigh the risks.

Miren Iturriza-Gomara, head of vxcialistoufjg.com’s rotavirus vaccine initiative, observes, “Rotavirus vaccines room a runaway public health success story. Castle are saving children’s lives and saving parents from heartache almost everywhere the world.”

“If regulators had removed rotavirus vaccines due to the fact that of the 1 in 100,000 threat of intussusception, around 900,000 youngsters would not be lively today.”

With the Johnson & Johnson COVID-19 vaccine, the crest are also greater. The pandemic continues to insurance claim hundreds that thousands of stays every day, and the hazard of new variants provides vaccination an urgent priority.

However, the Johnson & Johnson vaccine’s use in the United claims was paused after 6 women developed blood clots through low levels of blood platelets after ~ receiving the vaccine. While research study is ongoing, this threat so far shows up to be less than 1 in a million.

A danger of blood clots v low platelet counts, which might or might not be resulted in by the same system of activity as in the Johnson & Johnson vaccine, additionally appears to exist for the Oxford-AstraZeneca COVID-19 vaccine. This vaccine has been in use throughout Europe and also much of the people through the COVAX initiative. After countries started see a small increase in blood clots—estimated in ~ 4 in a million—several countries paused or restricted the vaccine’s use.

“Monitoring vaccine safety and security is big to any vaccination program,” note Dr. Kaslow.

“The quick identification of these blood clot situations with short levels of blood platelets underscores the prestige of reporting any type of adverse events and quickly determining if over there is a plausible attach to the vaccine. In ~ the same time, every medical treatment comes v some level the risk, and crucial role of public health officials is to evaluate the balance and to effectively connect both the benefits and also the threats to the public.”


In the situation of rotavirus vaccines, public health and wellness officials very closely analyzed the evidence before affirming that the lifesaving services of the vaccines outweighed the low-level risk of intussusception. Officials continue to interact the hazard to health treatment workers so they deserve to warn parental to look the end for intussusception in the rare opportunity that the does occur.

Additionally, since they knew the hazard was small due to data indigenous the clinical trials, officials did not pause rotavirus vaccine consumption during post-licensure surveillance. This decision allowed children to continue being protected from life-threatening diarrheal an illness while they continued to gather more data on rare side effects.

As scientists and officials sweet the risks and benefits that COVID-19 vaccines, the success that rotavirus inoculation is crucial lesson to keep in mind.

“The dangers of life-threatening blood clots with low blood platelet levels currently reported for the Johnson & Johnson and also Oxford-AstraZeneca vaccines appear to it is in rare, and also we know that at this time in plenty of countries the individual and also public health threats of not being vaccinated are extraordinarily high,” says Dr. Kaslow.

“Rotavirus vaccines are an instructive instance of the prestige of balancing rare-frequency threats with lifesaving benefits, and also of the prestige of very closely communicating the benefit-risk balance to health treatment providers and, many importantly, come the public.”
