Next Up In Video. So if temperatures rise around the planet, mosquitoes survive and breed longer, which increases the risk of spreading disease. Obviously other animals eat them, but not as an indispensable food source. And only the females bite. I allude to it in the book, and this is a touchy subject, but perhaps they are the pinnacle Malthusian check on uncontrolled human population growth.
This is something that scientists and biologists have been thinking about. Still, a lot of the CRISPR research [which alters the DNA of mosquitoes] is geared toward making mosquitoes harmless by making them incapable of carrying diseases, but not harming the mosquitoes themselves.
Eighty-five percent of what makes us attractive to mosquitoes is due to genetic factors. Can you explain? And what can we do to avoid bites? Blood type is one. According to studies, they prefer blood type O over A, B, or a blend. But there are other factors [that affect the chance of attracting mosquitoes].
Clean your feet. The bacteria on our feet is a mosquito aphrodisiac. Everywhere else on the skin is generally a deterrent, except feet. But most of it is hardwired into a genetic circuit board. There are myths about your hair color having an impact, or if you have darker skin or more leathery skin. None of that seems to be true. But the best advice? But the protection they provide against severe disease — resulting in hospitalization or death — remains strong for many people.
The exceptions are older people, who have seen a greater drop in efficacy over time, and people with compromised immune systems, for whom the vaccines are often not as effective to start with. They are the focus of the booster guidelines, along with workers in higher-risk settings. All of the Covid vaccines offer good protection against severe illness, but they are not equal. The Moderna vaccine has held up the best over time, including since the delta variant became dominant.
Antibody levels are not the only metric by which immunity is measured, but they are a useful proxy. The new FDA guidance does say that people should be okay mixing and matching different vaccines. Different vaccines also have different side effects, another consideration for booster shots.
Both of those side effects, though serious, have been rare, and the FDA said the expected benefits of a booster shot for each of the vaccines outweigh the risks. First off: The vaccines work. Recent waves of Covid hospitalizations and deaths have been concentrated in the remaining unvaccinated population. People who receive a vaccine are less likely to contract Covid in the first place, much less likely to develop severe symptoms, less likely to transmit the virus to other people, and less likely to develop long Covid.
There are going to be breakthrough cases. The recent death of former Secretary of State Colin Powell — who was fully vaccinated but immunocompromised because of blood cancer — served as a reminder that some people remain at risk so long as the virus is still circulating. The current federal guidance is concentrated on those people, to provide them more protection ahead of the winter.
