First of all, because you will protect yourselves from the possibility of severe illness or even death. Also, by getting vaccinated you will be doing your part to achieve a vaccination rate high enough to end the pandemic. Nobody knows exactly what percentage of the population needs to get inoculated for that to happen, but infectious disease experts put the number somewhere between 60% and 70% — perhaps even a little higher. Think of it as a civic duty to get your shots.
Q: So, when can I get mine?
It depends on your health status, age, and work. In the first phase, already underway, health care workers and nursing home residents are getting vaccinated. The 40 million Moderna and Pfizer doses expected to be available by year’s end should immunize most of them.
Next in line are people 75 and older and essential workers in various public-facing jobs. They will be followed by people ages 65-74 and those under 65 with certain medical conditions that put them at high risk. Enough vaccine could be available for the rest of the population by late spring, but summer or even fall is more likely. Already, some distribution bottlenecks have developed.
On the bright side, two other vaccines — one from Johnson & Johnson, the other from AstraZeneca and Oxford University — could win FDA authorization early next year, significantly increasing the supply.
Q: Once I’m vaccinated, can I finally stop wearing a mask and physical distancing?
No. Especially not early on, before a lot of people have been vaccinated. One reason for that is self-protection. The Moderna and Pfizer vaccines are 95% effective, but that means you still have a 5% chance of falling ill if you are exposed to someone who hasn’t been vaccinated — or who has been but is still transmitting the virus.
Another reason is to protect others since you could be the one shedding virus despite the vaccination.
Q: I’ve already had COVID-19, so I don’t need the vaccine, right?
We don’t know for sure how long exposure to the virus protects you from reinfection. Protection probably lasts at least a few months, but public health experts say it’s a good idea to get vaccinated when your turn comes up — especially if it’s been many months since you tested positive.
There’s been some talk among health officials of pushing those who’ve been infected in the last 90 days or so toward the back of the line, to ensure adequate supply for those who might be at higher risk.
Q: How long before our lives get back to normal?
“If everything goes well, next Thanksgiving might be near normal, and we might be getting close to that by the summer,” says Dr. William Schaffner, a professor of infectious diseases at the Vanderbilt University School of Medicine in Nashville, Tennessee. ”But there would have to be substantial acceptance of the vaccine and data showing the virus moving in a downward direction.”
