Las Vegas (KTNV) —Thursday, the US Centers for Disease Control and Prevention suddenly announced new guidance on wearing masks. Fully vaccinated Americans say they no longer need to wear masks in most cases, including indoors.

Following this announcement, 13 Action News discussed with Dr. Domenic Martinello, Chief Medical Officer at Southern Hills Hospital, to resolve the remaining COVID-19 vaccine confusion.

13 Action News asked Dr. Martinero the following question and received the following answer:

Q: Can I get infected with the virus even if I have been vaccinated against COVID-19? If so, what are the possibilities?

A: “The chances of getting the virus after being completely vaccinated depend on which vaccine you have vaccinated with. Therefore, the two major vaccines, the Pfizer vaccine and the Moderna vaccine, are more than 90% effective. It is known to have a so-called preventive effect, “symptomatic infection”. In terms of the fact that you can actually get infected with a virus, even if you are exposed to the virus and invade your body, you do not necessarily get sick. The immune system repels the virus fairly actively. In terms of having symptoms, it is more than 90% effective. It is also much more effective in preventing so-called “severe illness”, that is, hospitalization, and even more effective in preventing death. Not 100%. Everyone’s immune system reacts in exactly the same way. Some have weakened their immune system, while others are just unlucky and their bodies do not fight it off fast enough. But in reality, vaccines are so effective that they are the only way to reach what they call, herd immunity, or enough immunity to prevent spread. Therefore, when combined with 90% to 95% efficacy, a vaccine mixed with a large p percentage of the population that has it, now you reduce infections, reduce deaths, people get sick and miss jobs Reduced the risk of doing as easy as. And in the end, you get what they call “virus control.” At this level, these things are locally prevalent, but may not be pandemic.

Q: If the vaccine does not provide 100% protection against COVID-19, why bother to get the vaccine?

A: Such a pandemic is incredibly contagious. Looking at R0, which is a type of infectivity scale, it is on the order of 3. That is, all infected people infect about three others. It is highly contagious. And the only way we can get over it is vaccination. If you want to find out the mortality rate, the mortality rate of COVID-19 is about 1% compared to the vaccine. This has not been identified as a direct high level of mortality. We are looking at orders for 1 in 1 million compared to 1 in 100. If we dig deeper into these numbers, we need to consider more than just mortality, called morbidity from the disease. Therefore, COVID-19 disease appears to cause a lot of blood clots, which cause heart attacks and strokes in young and healthy people. I’ve seen people with permanent lung injury, permanent heart injury, and brain injury. So, looking deeper than 1% of those who die, we see many people undergoing permanent life-changing changes due to this disease. Comparing it with the risk of getting a very small vaccine shows why vaccines are a better alternative.

Q: Can I spread the virus to others even if I have been vaccinated against COVID-19?

A: “Vaccines are very effective in producing immunoglobulins in the body. This is how they work. These immunoglobulins are floating and bind to the virus. One of the things that vaccines don’t actually produce well. One, they call IgA, which predominates in the nasal cavity, mouth, throat, and gastrointestinal tract, so it actually infects locally in the nasal area or in the mouth and still spreads. The idea is that it can be done, and recent studies have stated that the infection rate in vaccinated people has been reduced by about half: R0 to 3, R0 to 1.5, or It usually infects three people, only one or two, and you need to think in order of size. If all of them are also vaccinated, the spread of the infection will be reduced. Therefore, the spread of the virus is possible, but it has been reduced. In most studies it is about half. You are vaccinated and the people around you are vaccinated. One of you is it. If you have, you have a 50% chance of spreading it, but you have a 90% chance of fighting it, some people have been vaccinated off or not get sick at all. In other words, the idea is to reduce the risk by about half, which is about 50% at the individual level, but on the other hand, if everyone is vaccinated, the risk is also significantly reduced, “says Dr. Martinero.

Q: Does wearing a mask reduce the risk of spreading this vaccination?

A: “There are certainly benefits. In other words, the obligation to use a mask comes from the perspective of preventing public health. If you really want to prevent the spread, you have vaccinations, social distance, wearing a mask, etc. All measures need to be taken. The reason mask obligations are now slowly being regained is that the amount of local illness is eventually sufficiently low and the risk is low, and the risk. When is below a certain threshold (usually between 5% and 7%), you will be able to mitigate some of these measures. Now, these measures will make the population more infected. When it comes to sex, they certainly need to go back to their original place. Of course, the biggest risk is when people start thinking. “Okay, these are a little loose.” And people are kind of Open the water gate. We do not want to put many people indoors in a small area without a mask. We want low-risk vaccinated people. Of these relaxing limits, especially outdoors, the risk of infection is already slightly lower. With the addition of mass vaccination, which is a low-incidence population, we can reach this point when we begin to return to normal, “says Dr. Martinero.

Q: I have been diagnosed with COVID-19 before, do I still need to be vaccinated? Why or why not?

A: In the short term, there is immunity called innate immunity. The unfortunate part is usually the development of a kind of short-lived antibody against one very specific virus. Studies show that many people exposed to some of these variants after being infected with COVID are still infected with the variants. One of the problems is that immunoglobulins are not produced reliably or for specific sources. One person may have nucleocapsid antibodies and another may make antibodies to the peaplomers, but vaccines target highly specific targets, which are these conserved regions of the peaplomers. On the other hand, it produces a very specific antibody. Therefore, we find that the vaccine is also effective against most of these variants, compared to innate immunity, which may or may not develop immunity to South African and British variants. .. And that’s why it’s even more important for people infected with COVID to go out and get vaccinated. Also, if you are not infected with COVID, go out and get the vaccine, “says Dr. Martinero.
