text: The Covid-19 vaccine is set to be administered sometime in the next few days right after the U.S. Food and Drug Administration approved the first vaccine for Emergency Use Authorization (EUA)
  Thus far, the vaccine makers Pfizer, Moderna and Astra Zeneca, who have finished their trials and asked for approval around the world, offer their vaccine in two shots. The doctors said those who get the vaccine will have some protection after the first shot.
  Data has shown that the vaccine starts working immediately after the first dose and has an efficacy rate of 95 percent 7 days after the second dose. This means that about 95 percent of individuals who get the vaccine are protected from becoming seriously ill with the virus.
  “You get a second injection after one month, or 3 weeks right after the first one, as in the case of Pfizer/ Biontech vaccine” Novak said. “This boosts the response even further, so you have extra antibodies. We absolutely know that the second shot boosts the immune response. This is more likely to last longer after you get both shots.”
  “The vaccine targets the spike protein of the virus,” said Dr. Richard Novak, chief of infectious diseases at the University of Illinois-Chicago. The vaccine does not have live virus. It contains mRNA from the spike protein of SARS CoV-2. “When the vaccine gets into your cells, the cells read the mRNA of the protein which is shown on the surface of the cell,” Novak said. “The immune system sees that and recognizes it doesn’t belong there and starts to build an immune response to it.” The body recognizes the manufactured spike protein to learn how to react when the actual thing takes hold and sets the immune system into overdrive. But when that occurs, it can cause inflammation.
  Vaccine recipients may feel a response or mild effects immediately including headache, headache, body aches and fatigue. But not everyone has a reaction. The vaccine is not for children under age sixteen and pregnant women. It is also not recommended for persons with certain health conditions. Dr. Novak, who ran the Chicago arm of the Moderna trial also monitored patients after their injections. He said just because people don’t get side effects, their body is still working to search and destroy the virus. And very rapidly, vaccine recipients have immunity.
  Experts want to learn more about the protection the Covid-19 vaccine offers and how long the immunity lasts before altering safety recommendations. For now, the Centers for Disease Control and Prevention still recommends following precautions for avoiding infection with the Covid-19 virus.
