|    'Single dose' J&J vaccine hits roadblock    |

      From: brewnoser2@gmail.com              Read the last sentence of this article. Every reason to be careful -       especially if you're on any blood-thinning medications. And note the status of       AstraZeneca in the U.S.       ____________________________________________       The Associated Press ยท Posted: Apr 13, 2021              U.S. recommends 'pause' for Johnson & Johnson vaccine over clot reports              More than 6.8 million doses of the J&J vaccine have been administered in the       U.S              U.S. health officials are recommending a "pause" in administration of the       single-dose Johnson & Johnson COVID-19 vaccine to investigate reports of       potentially dangerous blood clots.              More than 6.8 million doses of the J&J vaccine have been administered in the       U.S., the vast majority with no or mild side effects. But in a joint statement       Tuesday, the Centers for Disease Control and Prevention and the Food and Drug       Administration said        they were investigating unusual clots in six women that occurred six to 13       days after vaccination.              The clots occurred in veins that drain blood from the brain and occurred       together with low platelets. All six cases were in women between the ages of       18 and 48.              The reports appear similar to a rare, unusual type of clotting disorder that       European authorities say is possibly linked to another COVID-19 vaccine not       yet cleared in the U.S., from AstraZeneca.              U.S. federal distribution channels, including mass vaccination sites, will       pause the use of the J&J shot, and states and other providers are expected to       follow. The other two authorized vaccines, from Moderna and Pfizer, make up       the vast share of COVID-       19 shots administered in the U.S. and are not affected by the pause.              The single-dose vaccine has been approved in Canada, but the country has not       yet received any doses.              'Abundance of caution'              The CDC's Advisory Committee on Immunization Practices will meet Wednesday to       discuss the cases and the FDA has also launched an investigation into the       cause of the clots and low platelet counts.              "Until that process is complete, we are recommending a pause in the use of       this vaccine out of an abundance of caution," Dr. Anne Schuchat, principal       deputy director of the CDC, and Dr. Peter Marks, director of the FDA's Center       for Biologics Evaluation        and Research, said in a joint statement.              They are recommending that people who were given the J&J vaccine who are       experiencing severe headache, abdominal pain, leg pain, or shortness of breath       within three weeks after receiving the shot contact their health-care provider.              U.S. health authorities cautioned doctors against using a typical clot       treatment, the blood-thinner heparin. "In this setting, administration of       heparin may be dangerous and alternative treatments need to be given," the FDA       and CDC said.              European authorities investigating the AstraZeneca cases have concluded clots       appear to be similar to a very rare abnormal immune response that sometimes       strikes people treated with heparin, leading to a temporary clotting disorder.              Officials say they also want to educate vaccine providers and health       professionals about the "unique treatment" required for this type of clot.              Johnson & Johnson said it was aware of the reports of "thromboembolic events,"       or blood clots, but that no link to its vaccine had been established.              "We are aware that thromboembolic events including those with thrombocytopenia       have been reported with COVID-19 vaccines," said Johnson & Johnson in a       statement. "At present, no clear causal relationship has been established       between these rare events and        the Janssen COVID-19 vaccine."              Single-dose vaccine              The J&J vaccine received emergency use authorization from the FDA in late       February with great fanfare, with hopes that its single-dose and relatively       simple storage requirements would speed vaccinations across the country. Yet       the shot only makes up a        small fraction of the doses administered in the U.S. as J&J has been plagued       by production delays and manufacturing errors at the Baltimore plant of a       contractor.              Last week, the drugmaker took over the facility to scale up production in       hopes of meeting its commitment to the U.S. government of providing about 100       million doses by the end of May.              Only about nine million of the company's doses have been delivered to states       and are awaiting administration, according to CDC data.              Until now, concern about the unusual blood clots has centred on the vaccine       from AstraZeneca, which has not yet received authorization in the U.S. Last       week, European regulators said they found a possible link between the shots       and a very rare type of        blood clot that occurs together with low blood platelets, one that seems to       occur more in younger people.              The European Medicines Agency stressed that the benefits of receiving the       vaccine outweigh the risks for most people. But several countries, including       Canada, have revised their recommendation around who should receive the       vaccine.              The J&J and AstraZeneca vaccines are made with the same technology.       [viral vector]       Leading COVID-19 vaccines train the body to recognize the spike protein that       coats the outer surface of the coronavirus. But the J&J and AstraZeneca       vaccines use a cold virus, called an adenovirus, to carry the spike gene into       the body.              J&J uses a human adenovirus to create its vaccine while AstraZeneca uses a       chimpanzee version.              https://media.tenor.com/images/99470844aa5ee3c63c8939815f4d3a5d/tenor.gif              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
