Scientists studying the COVID-19 outbreak in Massachusetts have been vaccinated with so-called breakthrough infections in another intriguing setback for the country’s efforts to eradicate the coronavirus. Concludes that they had about the same amount of coronavirus as those who did not. shot.
Health officials released details on Friday That study, This is the key to this week’s decision by the Centers for Disease Control and Prevention to allow vaccinated people to wear masks indoors in some parts of the United States where delta mutants are contributing to the proliferation of infections. Was recommended. The authors said the findings suggest that the CDC’s mask guidance needs to be extended to include the entire country, even outside the hotspots.
Findings can overturn past thoughts about how the disease spreads. Previously, infected vaccinated people were thought to have low levels of the virus and were less likely to infect others. However, the new data show that this is not the case for the delta variant.
Outbreaks in Provincetown, a seaside tourist destination in Cape Cod, the county with the highest immunization rates in Massachusetts, have included more than 900 cases so far. About three-quarters of them were fully vaccinated people.
Travis Dagenais, one of the many vaccinated people, said, “Watch out for the wind,” and having a long night party in the crowd on the holiday of July 4 is a hindsight mistake. did.
“The main public message was that the vaccine would return to normal,” said a 35-year-old Boston resident on Thursday. “Unfortunately, I learned that this is just a few steps towards normal, not the 0-60 that we think we’ve done.”
Dagenais believes he was vaccinated in a few days by relieving the worst of the flu-like symptoms. He recovered.
Massachusetts, like many states, lifted all COVID-19 restrictions in late May prior to the start of Traditional Memorial Day in the summer season. Provincetown has revived everyone’s indoor mask requirements this week.
Leakage of internal documents about breakthrough infections and delta variants has led to the state’s coronavirus, including the CDC recommending masks for everyone and demanding vaccines from doctors and other healthcare professionals. It suggests that you may be considering other changes to your advice on how to fight.
The first delta variant detected in India causes more infectious diseases than the common cold, flu, smallpox, and Ebola virus, and is as infected as chickenpox, according to documents referring to the case in Providetown. There is sex.
The document was obtained by The Washington Post. As they point out, the COVID-19 vaccine is still very effective against delta mutants in preventing serious illness and death.
Provincetown outbreaks and documentation highlight the major challenges the CDC faces in encouraging vaccination, and that breakthrough cases can occur and are rare but potentially contagious. I admit it.
These documents seem to be issues for CDC staff to use with the general public. At one point, he said, “I admit that the war has changed.” This is a clear reference to the growing concern that millions of vaccinated people could cause widespread spread. A government spokeswoman declined to comment on the document.
The White House on Friday defended its approach to increasing viral cases and changing public health guidelines, emphasizing the need for vaccination, and repeatedly postponed it to the CDC.
“The most important point is actually very simple,” said White House spokeswoman Karine Jean-Pierre, who needs more people to get vaccinated.
Pressured to change the guidance, Jean-Pierre reiterated, “We will not make such a decision from here.”
According to the leaked document, people with breakthrough infections account for an increased part of hospitalization and in-hospital mortality in COVID-19 patients, consistent with the epidemic of delta mutants.
Experts generally agreed with the CDC’s revised indoor masking stance, but said reports of provincetown outbreaks did not prove that vaccinated people were a significant cause of new infections. There are also people.
“The (CDC) recommendation has scientific validity, but it was not derived from this study,” said Jennifer Nuzzo, a public health researcher at Johns Hopkins University.
The CDC report is based on approximately 470 COVID-19 cases related to Provincetown festivals, including dense indoor and outdoor holiday events in bars, restaurants, guesthouses, and rental housing. Researchers ran tests on some of them and found about the same level of virus in fully vaccinated and non-vaccinated people.
Three-quarters of infections were fully vaccinated individuals. About 80% of fully vaccinated people experience symptoms, the most common being cough, headache, sore throat, muscle aches and fever.
Dagenais said he began to feel sick the night he got home and initially chalked a long night party at a nightclub in a packed provincetown.
But as the days went by and fever, chills, muscle aches, and malaise began, he realized that it was something more.
Dr. Angela Rasmussen, a virologist at the University of Saskatchewan, said in a report that a measurement researcher used to assess the amount of virus an infected person had actually infects others with the virus. He said he did not indicate if he was present.
CDC officials say more data is coming. They track groundbreaking cases as part of a much larger study that involves long-term tracking of tens of thousands of vaccinated and unvaccinated people across the country. I am.
