Do Vaccines Also Protect Against Long COVID?

Do Vaccines Also Protect Against Long COVID?

Photo: OlegRi (Shutterstock)The most important thing that the COVID vaccines do is prevent deaths and severe illness from COVID-19. The next most important thing they do is prevent many cases of milder illness—a job they’re not perfect at, but it’s still far better to be vaccinated than not. But what about long COVID, the still-mysterious long-term symptoms that can follow some coronavirus infections?Long COVID is still not well understoodOne of the reasons it’s hard to get a straight answer on this question is because long COVID itself is hard to define and has been hard to study. Symptoms of long…

Why Your Doctor Doesnt Want to Give You an Off Label COVID Vaccine

Why Your Doctor Doesnt Want to Give You an Off Label COVID Vaccine

Photo: goodluz (Shutterstock)When Pfizer’s COVID-19 vaccine was approved in August, it was only approved for ages 16 and up as a two-dose series. But since fully-approved vaccines and medications can be used “off label,” many of us started wondering if providers could administer the vaccine to children or give boosters to people who wouldn’t otherwise qualify for them. Unfortunately, that’s not likely to be the case. The reason relates to some specific government paperwork, but first let’s talk about what “off label” means.What does “off label” mean?Drugs (and vaccines) are FDA approved for specific purposes. But providers are allowed to…

Where Do COVID Variants Come From, Anyway?

Where Do COVID Variants Come From, Anyway?

Photo: Brandon Bell (Getty Images)Variants of the virus that causes COVID-19 didn’t really make news until this year, despite the virus spreading around the globe all through 2020. There’s some misinformation out there blaming the vaccine itself for these variants, but that seems to be based on a misunderstanding. Let’s explore the facts.The truth: More infections = more variantsThere’s a saying in biology that “nothing makes sense except in light of evolution.” And that’s definitely true here. As anything reproduces—whether viruses or human beings—some of the individuals will be a little different from their parents. DNA isn’t copied exactly perfectly,…

Does the COVID-19 mRNA vaccine affect breastmilk?

Does the COVID-19 mRNA vaccine affect breastmilk?

New research investigates whether the mRNA from the COVID-19 vaccines can be passed on to infants through breastmilk. The development and administration of SARS-CoV-2 vaccines is helping to reduce transmission of COVID-19, and these vaccines have been an integral part of combating the global COVID-19 pandemic.  The first approved SARS-CoV-2 vaccines were mRNA vaccines, which use mRNA from the SARS-CoV-2 spike protein to train the immune system to recognize and attack the pathogen without the risk of COVID-19 infection.1 The two mRNA vaccines that are currently approved for COVID-19 are BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna).  Current research suggests that both…

Should you skip your second dose of COVID-19 vaccine?

Should you skip your second dose of COVID-19 vaccine?

Vaccine uptake has varied worldwide, with some countries still experiencing higher rates of first COVID-19 vaccine dose compared with a second dose, suggesting some people may be skipping their second dose of the COVID-19 vaccine. A recent study suggests why this might not be a good choice. Conventionally, the approval of new vaccines worldwide has always been a lengthy and systematic process. From an immunological perspective, new vaccines must be successful at inducing the production of neutralizing antibodies, made by specific immune cells called B cells, that block a virus from infecting the body.1 Pfizer and Moderna COVID-19 vaccines The…

There may be a gene for COVID-19 resistance

There may be a gene for COVID-19 resistance

Evidence from a recent study suggests that a specific gene may provide some resistance to severe symptoms of COVID-19. According to the study, the genetic make-up of those who experience severe COVID-19 symptoms, versus those who are asymptomatic, significantly differ at one gene location. The study found a significantly higher frequency of the HLA-DRB1*04:01 gene in asymptomatic individuals. This potential gene for COVID-19 resistance is a version – allele – of the human leukocyte antigen (HLA) family of genes, which are involved in immune system response. The research group from Newcastle University in the United Kingdom enrolled 49 patients in…

Specific antibodies may be effective against multiple coronavirus types

Specific antibodies may be effective against multiple coronavirus types

Patients who have been exposed to a coronavirus may produce a versatile, cross-reactive coronavirus antibody; this may be useful for the eventual development of a broad-acting vaccine. There are seven human coronavirus types, of which, four cause the common cold, named OC43, HKU1, 229E, and NL63. Most people become infected with at least one of these four coronaviruses at some point in their lives. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is another member of the coronavirus family that causes COVID-19. Infection with the cold-causing coronaviruses may lead to immune memory. This could potentially impact on the immune response to…

COVID-19 and heart attack risk

COVID-19 and heart attack risk

Does a positive diagnosis of COVID-19 increase the risk of heart attacks for those with pre-existing atherosclerotic cardiovascular disease (ASCVD) or familial hypercholesterolemia (FH)? It has been shown that higher rates of COVID-19 deaths can be associated with hypertension, heart failure, and cardiovascular disease. However, there were fewer patients reporting acute myocardial infarction (AMI), or heart attacks, when visiting hospitals during the pandemic. Researchers from across the United States gathered the data from approximately 55 million individuals for this study. They were divided into six categories based on the information available, which included combinations of diagnosed FH, probable FH, diagnosed…
