People born before 1989 may need another measles vaccine

The US is in the middle of the worst measles outbreak since Of course, even though the majority of the victims are children whose parents chose not to vaccinate them, or people who decided to vaccinate, there are even some people who get the measles vaccine as children depending on their age are still exposed to real risk.

Earlier this month, Israeli public health officials reported that a 43-year-old Israeli woman had fallen into a deep coma as a result of measles infection, a rare complication of the viral flu-like illness. Israel is currently struggling with its own outbreaks of measles, and just like in the US, it is largely due to transmission between unvaccinated individuals (the woman was a flight attendant on an airline that regularly flies between the US and Israel, she says) Countries have signed). But the woman herself was vaccinated, if not to the degree that many people are today.

Today, children over the age of one receive two vaccinations combining measles, mumps and rubella or MMR. But it was not until the 1980s that people in the US and elsewhere were given only one shot. It was not until 1989, after a series of outbreaks, that US health experts approved a two-dose MMR schedule. The MMR vaccine, like so many others, is not perfect for measles, even with two shots (97 percent), but still better than a shot (93).

This does not necessarily mean that all born before 1989 should fly out immediately and be vaccinated again with MMR. For example, the Centers for Disease Control and Prevention only recommend that people vaccinated between 1963 and 1967 receive a copy of the current MMR vaccine, as this older version was not very effective. The CDC also recommends that adults who are somehow not yet vaccinated receive at least one shot of protection.

However, we know that vaccine immunity against measles may decrease years or decades later, even in people who have had two shots. Interestingly, research has also shown that the growing outbreak of mumps in adolescents can be associated with a much faster MMR vaccine immunity, which has led some scientists to be asked for routine screening at the age of 18. Meanwhile, the CDC says that public health officials can recommend a third booster for people who are at an increased risk of mumps, such as those living near a recent outbreak.

But what if you live in an area where a measles outbreak is occurring? As far as we know, having a third MMR scan for measles alone has a small advantage. However, if you have only had one MMR (or do not know your vaccination history), it is not bad if you go to the doctor and ask him about the vaccine, especially if you live in one of the five states (California, Michigan, New Jersey , New York and Washington), where an outbreak is currently raging. At least on Twitter, vaccinated individuals, including physicians reported that they went to their doctor to test their antibody levels and, in some cases, received a booster when those levels were particularly low.
