Last weeks column on the Florida surgeon generals cavalier approach to controlling his states burgeoning measles outbreak prompted many readers to express a concern that I share: anti-vaccine sentiment is growing and threatens decades of public health progress.

Joseph from Oregon has a different view. Youve been writing that people should gauge individual risk when it comes to covid, he wrote. Why isnt it the same with measles? Your article says that the vaccine is 97 percent protective. Vaccinated kids dont need to worry, so why isnt it up to parents to decide whether to give their kids the shot?

Joseph raises an interesting point that goes to the fundamental tension in public health of weighing individual freedom vs. whats best for society. Individual freedom should generally take precedence, but there are some circumstances where policymakers have to decide in favor of protecting the public.

I was thinking about this question when I took my kids to an indoor play gym over the weekend. For those unfamiliar with the concept, think of a regular jungle gym but bigger and all indoors, with slides, ball pits, trampolines and multilevel climbing structures. The ones in my area become very crowded, with hundreds of kids and parents packed into relatively small spaces.

As soon as I signed my 6-year-old son in, he ran off with some friends and disappeared in the throng of excited kids. I wasnt so worried about keeping an eye on him, but I did worry about my 3-year-old daughter. I knew that if I let her out of my sight, it could take a while to find her.

My husband told me not to worry; in his view, this kind of play is exactly what these indoor gyms are designed for. Another mom who overheard our conversation agreed with him; her young child was playing wherever she wanted, without her mom hovering over her as I was doing with my daughter. On the other end of the spectrum are parents who wouldnt even think to come to these indoor gyms for safety reasons.

All of these are reasonable individual decisions. The fact that they should be made by parents about their own kids is something few would take issue with.

Now lets take a totally different scenario. Lets say that there were a couple of kids who were hitting other kids and pushing toddlers off climbing structures. Even if their parents had no issues with this behavior, they pose a threat to others, and few would argue against intervention.

The question of where measles and covid-19 lie on this continuum of individual choice comes down to three factors: how dangerous is the disease, what is the risk posed to others and how effective are the mitigation measures.

While Joseph is right that the measles vaccine is highly protective, it is not 100 percent effective, which means that some vaccinated individuals might still get infected. Also, there are babies and young children who are too young to be vaccinated. The unvaccinated, if exposed to measles, have a nearly 90 percent chance of becoming infected, and infection poses many harmful consequences including a 1 in 5 chance of hospitalization, permanent neurological defects and death.

Crucially, targeted mitigation measures of boosting vaccinations and quarantining exposed people work to contain measles, as they have in recent outbreaks in New York, Ohio and Pennsylvania. In addition, its possible to stop measles from propagating by achieving herd immunity, which is what the United States has been successful in doing.

This is not the case with covid. The nature of the coronavirus is such that no level of population immunity will stop the disease from circulating. In addition, the coronavirus vaccines, while protective against severe disease, have limited effect on reducing infection. Large-scale population measures such as required masking, vaccines and isolation periods have not contained the virus, and indeed have spawned such substantial backlash that other public health interventions including the measles, mumps and rubella (MMR) vaccination are now harder to implement.

To go back to the indoor play gym analogy, the interventions required to stop measles in Florida are akin to stopping a couple of kids from playing until they are no longer harming others. Yes, it restricts their freedom, but its a temporary measure imposed on a small number of people because the risk to others outweighs the individuals right to self-determination.

On the other hand, using societal interventions to try to control covid at this point would be more analogous to shutting down all playgrounds in perpetuity, knowing that the aggressive behavior would continue outside their premises. The interventions are wrong not only because most would perceive them as government overreach, but because they simply wont work.

This is why it makes sense to me to view risks around covid as individual decisions, and why the risk-benefit calculation is different for preventing the resurgence of previously eliminated deadly diseases such as measles and polio.

As Rose from Minnesota reminds us, I remember all too well the days when every child got measles and chicken pox and our parents kept us out of public pools because they feared we would be next to be paralyzed from polio. We all lined up and got our shots because our parents saw what these diseases can do. We simply cannot afford to go back in time. I couldnt agree more.
