Fact Check: The COVID-19 Vaccine – Why People Miss the Second Shot | World | Breaking News and Global Perspectives | DW



Why do millions of Americans miss a second COVID-19 shot?

According to a recent report in New York Times The reasons for not having a second dose vary from fear of possible side effects from vaccination to the belief that a single dose is sufficient to protect against the coronavirus to the logical barrier. Sticks outside of the individual’s control, such as canceled appointments and pharmacies do not store doses. Of the correct brand of vaccine

The Centers for Disease Control and Prevention (CDC) data, cited in the NYT report and other media, have summarized in headlines highlighting millions of Americans are not returning a second dose. What some of these articles are less readily known is that while 8% of Americans do not return a second dose for a number of reasons, this means that 92% of Americans follow the official dosing schedule. Stay.

Dr. Angela Rasmussen is a virologist at the Vaccine and Infectious Disease Organization (VIDO). “I think so. [CDC data] It̵

7;s great encouragement, while 8% are still millions more. But that also means that most people will come back for a second vaccination, which is very good compared to the other vaccines, ‘she told DW.

Rasmussen recently faced two dilemmas of herself. She was appointed to film. BioNTech-Pfizer In washington state But was scheduled to move to Canada to start a new job before she was given a second dose within the recommended timeframe. Instead of receiving BioNTech-Pfizer Her first shot was the Johnson & Johnson vaccine, a single vaccination. The experience made her 8% sympathize with missing a second dose.

“If it’s hard for me to figure out how I’m going to get a second shot and I’m a virologist, I think it can be very difficult for people who don’t have access to transportation or for people who don’t have access to transportation.” May not understand the internet as it should be, “she said.

Why don’t people take the second dose?

Experts believe there are many reasons people might miss a second dose. “Someone reading and guessing that a single bullet is enough,” Rasmussen said, which could make them feel wrongly safe. It makes people less inclined to take the second dose, which is the post-vaccination symptoms.

“Some people may have unwanted side effects associated with the first shot and decide for themselves they don’t want to experience it again in the second shot,” she said. Little may have forgotten that they needed a second shot.

“I think people are advised by their health care provider not to get a second vaccination, and that is if they have allergies or have a poor history of getting the booster vaccine. Which may be a minority But I think some cases People for medical reasons are advised not to get a second shot, “Rasmussen said.

New York protesters hold signs protesting racism in vaccination.

Natural racism may prevent people from getting vaccinated without some African Americans being able to access them.

Demographic factors can play a role, too, said Dr. Lisa Cooper, head of the Johns Hopkins Center for Health Equality, said African Americans face structural barriers to accessing even the first dose of vaccine.

“If you’re an older black person, you probably don’t have a beautiful cell phone or computer, so you’re most comfortable using a regular phone – but some vaccination locations don’t have a dial-in number and the only way to register. It’s online, ”she said to DW. But you find the vaccination site on the other side of town and you don’t have a car – do you want to take public transport between COVIDs and will incur additional costs? Money to do all those things “

Economic concerns also play a role in vaccine hesitation. Many US workers say they need to be vaccinated. But it is not always supported by employers. To address this issue, US President Joe Biden has urged employers to provide vaccination leave and offer tax credits to small and medium businesses to cover expenses.

Is one time enough?

Experts have repeatedly explained that in order to have longer and better COVID-19 protection you need two shots, there is encouraging information to suggest that at least in the short term, the first shot will give you a shot. Some protection But the defensive timing is unclear – and it’s not as good as the second shot, as Toronto-based physician Michael Warner recently pointed out on Twitter.

Two recent studies from the UK’s National Statistical Office and the University of Oxford have found that people experience strong antibody responses after being jammed. One study found a 72% reduction in infection with symptoms after vaccination. BioNTech-Pfizer or AstraZeneca once after ingestion. BioNTech-Pfizer Twice showed a 90% reduction in symptomatic infections.Because of the time of the release of the AstraZeneca vaccine, no data on the second dose was available.

Koen Pouwels, a study author and a researcher at the University of Oxford’s Nuffield Department of Population Health, said getting a second vaccine would lead to longer protection, as well as better protection from COVID-19.

“As with any primary infectious disease [after the first dose] “If you look at the antibody response, the decline is relatively fast. A second dose is very protective and can make your antibody levels much higher, especially in the elderly, ”he told DW.“ Getting a second dose is very important. ”

It’s not that the second shot won’t work if you wait longer before it gets. That is, you may not have the protection you thought you had during the time between shots. “What people may be missing is that the second shot is really necessary to stimulate the immune response in these long-term memory,” Rasmussen said.

Is a single vaccine enough for COVID survivors?

A US study conducted by Cedars-Sinai Medical Center, which involved more than 260 people, showed that “the Pfizer-BioNTech vaccine” has been shown to be effective. A single dose for a person previously infected with COVID-19 produced an immune response similar to those who received both of these, the recommended sequence-dose sequence.

According to the researchers, the data suggest that a second dose may not be needed for people recovering from coronavirus infection. The question is, how effective is a single dose of the drug?

“Many people have been infected with COVID-19 and vaccine availability is limited in most regions, so a single dose of COVID-19 can speed up the number of people who are covered by vaccination and enable access to vaccinations. Community level that stopped the spread of infection, ”said Jonathan Braun, professor of medicine at the F. Widjaja Foundation Inflammatory Bowel and Immunobiology Research Institute at Cedars-Sinai and co-author of the study, told DW. Email

Research conducted by the Penn Institute of Immunology also found that people recovered from the infection showed strong antibody responses after receiving the first mRNA vaccine, in a press release, E. John Wherry, an immunologist and co-author. Of the discovery said “These results are encouraging for both short-term and long-term efficacy of the vaccine, and this enhances our understanding of the immune response of mRNA vaccines through B-cell memory assay.” It helps build long-term immunity.

In Germany, the Immunization Committee (Stiko) recently updated the findings to reflect new data, suggesting that for individuals with confirmed SARS-COV-2 infection that resulted in Caused COVID-19 ”a single vaccination should not have been previously considered. After more than 6 months of recovery due to existing immunity following exposure to infection, a strong immune response occurs as a result of one booster vaccination.All approved COVID-19 vaccines can be used in the vaccination of the patient. “
