Has there been an upsurge in covid cases?
There has been a bit of a spike in COVID cases recently, likely due to the emergence of a new variant called BA.2.86 (also known as Pirola). This new variant has some characteristics that make it more transmissible than previous variants, and it's causing an uptick in hospitalizations in some areas. However, the good news is that vaccines are still effective against this variant, and many people are well-protected due to prior infection or vaccination. It's important to keep an eye on the situation and take precautions like masking and testing if you feel sick. But overall, the situation isn't dire and there's no need to panic. It's just a reminder that COVID is still around and we need to remain vigilant!

Are the newest vaccines monovalent?
Monovalent vaccines are specifically designed to target a single strain of a virus, in this case, the original strain of SARS-CoV-2. This approach was chosen because it allows for a faster development process, and it also means that the vaccine can be easily updated in the future if new variants emerge. However, there are also bivalent vaccines in development that target two strains of the virus. These vaccines are thought to provide broader protection, but they take longer to develop and test. So, basically, it's a trade-off between speed and breadth of protection.
Despite targeting the original strain, they've actually been shown to still be pretty effective against the newer variants, like BA.2.86. The reason for this is that these newer variants have enough similarities to the original strain that the immune system can still recognize and fight them off. It's kind of like recognizing a distant cousin who has the same nose and hair color as your uncle, even though they're not identical twins. It's not 100% protection, but it's definitely better than nothing!
