COVID vaccines remain safe and effective. They prevent severe illness, hospitalization, and death. Additionally, even among the uncommon cases of COVID among the fully or partially vaccinated vaccines make people more likely to have a milder and shorter illness compared to those who are unvaccinated.

It is important to bear in mind that the amount of virus it takes to cause infection is only one part of the story. How the body responds to the virus can also be critical.
This is because the immune response to a virus can be both beneficial and harmful. On the other hand, if the immune system is over-activated, it can damage healthy tissues. There is a long list of medical conditions that can increase the chances of having a severe case of COVID, from diabetes to high blood pressure. But what about factors such as exhaustion or extreme stress? We expect many frontline medical staff to be under significant pressure in the coming weeks and months; could this affect their susceptibility?
Sleep deprivation has been shown to affect your chances of getting infected with rhinovirus, also known as the common cold virus. Scientists in Pittsburgh, Pennsylvania, monitored sleep patterns in adults over a week and then exposed them all to rhinovirus. Those people who slept fewer than five hours a night were significantly more likely to develop a cold than those who slept seven or more hours.
But we can speculate that the immune responses of severely overworked healthcare workers will not be optimal compared with a well-rested person at home. This could be an additional factor explaining why more frontline staff are seemingly becoming infected with COVID Computer viruses are about as diverse as computer users.
Most tech-savvy folks are familiar with the standard forms of malware: phishing scams, adware, spyware, viruses, worms and the like. However, as technology advances, so do cybercriminals, and they are attempting to fly lower under the radar to get your information.

Exploit kits are generally what they sound like - a malicious toolkit that searches your computer for software that has not been updated. This can happen by visiting websites that have malvertising on them. Malvertising can be found on any website, trusted or unknown, and it uses online advertising by embedding malicious code in legitimate advertisements. Recently, Yahoo was a target of this by hosting malicious ads that redirected users to websites hosting these kits.
Exploit kits are not always found in malvertising, however. This is why it is very important to make sure all of your software is up to date. Ransomware is a program that will target important files such as photos and documents and encrypts them, blocking the user from accessing them.
The user is then sent a message demanding payment to unlock the files.
