Can Vaccines Stop The Virus From Spreading
The available vaccines alone cannot stop the spread of the virus. But vaccination, combined with basic preventive measures such as proper hygiene, face masks and social distancing where needed, lowers transmission significantly. Simply wearing a face mask reduces the incidence of the coronavirus by more than 50%, according to a study based on data from 200 countries and published in the medical journal BMJ. For López-Hoyos, this is clearly the reason why countries such as Austria and Germany are seeing such a sharp rise in infections. In these countries, fewer people are vaccinated, and despite this, they relaxed basic protection measures earlier. This should make us think that we need to maintain the use of face masks and the rest of the basic hygiene measures, because right now, it is the only way we have to curb the transmission of the virus, he says.
If I Get The Shot Can I Still Get Covid
Registered nurse Katherine Noel prepares a dose of Moderna COVID-19 vaccine to give to staff at the Wardenburg Health Center on the CU Boulder campus.
With Moderna and Pfizer ramping up production, Johnson & Johnson poised to earn emergency use authorization from the Food and Drug Administration, and the White House promising 13.5 million vaccine doses per week to states, many see a light at the end of the COVID-19 tunnel.
As of Wednesday, 14.5% of Coloradans had gotten at least one shot and 6.8% were fully vaccinated.

On Tuesday, March 2, at the Campus Q& A, McQueen and Jennifer McDuffie, associate vice chancellor of Health and Wellness, will join other guests for a webinar on vaccine safety.
Through the use of vaccines, we have the ability to end this pandemic, said Matt McQueen, director of epidemiology for the Pandemic Response Office at CU Boulder.
But with increased vaccine availability have also come questions about how they work and what they do and dont do. CU Boulder Today caught up with McQueen, a professor of integrative physiology, to get some answers.
Can I Still Get Vaccinated If I Have A Cold
People with mild cold-like symptoms are not prevented from getting the vaccine. However, if they are not feeling well, their symptoms just started, or their symptoms are getting worse, they may want to delay vaccination until they feel better otherwise, they might not be able to tell effects of illness from those of the vaccine. If they are uncertain, they should speak to their doctor, who has the benefit of their medical history and will be in the best position to help them weigh the potential pros and cons.

Does Being Fully Vaccinated Offer Good Protection Against Covid
The COVID-19 vaccination booster programme is well underway in the UK, with an increasing number of eligible people being offered their third jab. According to NHS England, more than five million people have had a third vaccine since the vaccination programme began administering them last month.
Multiple studies suggest being vaccinated significantly reduces the chance of testing positive for COVID-19. In October, the results of an ONS COVID-19 infection study showed that being fully vaccinated provided the best protection. Higher protection still was found among those who had experienced a past infection followed by two vaccines.
Two doses of either the Pfizer or the AstraZeneca vaccine provided a similar level of protection to prior natural infection when the Delta variant was dominant, the research found. However, it also showed that vaccines were slightly less effective against the Delta variant compared with the Alpha variant.
“The vaccines give much better protection against severe disease than against mild disease or infection with no symptoms, so some vaccinated people will still get infected,” he adds. “But they get infected at a lower rate than unvaccinated people.”
Will The Current Pfizer
All viruses mutate over time but several variants of SARS-CoV-2 with multiple mutations, particularly in the gene that encodes for the spike protein, have been identified that have become more prevalent, including variants from the United Kingdom, South Africa, and Brazil. The best evidence of whether the Pfizer-BioNTech and Moderna vaccines provide less protection against these variants will be if we identify people who become infected with one of the variants after receiving two vaccine doses. Before that, we can learn from studies in the laboratory. Recent studies suggest that both vaccines are effective against these variants but may be slightly less protective against the South African variant. However, much remains to be learned. Both vaccine manufactures are working on modified vaccines to better protect against the South African SARS-CoV-2 variant.

Dr Frank Mcgeorge Answers Covid Questions
Since the coronavirus pandemic began, Dr. Frank McGeorge has been keeping viewers up-to-date and informed on all fronts. Hes been answering your questions about the vaccine, the vaccination process and more.
My family and I have gotten our booster shots about six months ago. With the omicron vaccine supposedly coming out in March, would you recommend getting the fourth shot now or wait for the omicron vaccine?
If you are currently fully vaccinated and boosted there is no reason for an additional shot at this time. I would wait for future CDC recommendations, especially with the potential for variant specific vaccines in the future.
Now that the cases are going down from the omicron variant, should we still stick to the KN95 masks or can we go back to the daily disposable masks?
If you are going to mask, using the best mask available to you is always the best option. But comfort is also an important factor and youre right to suggest that we should adjust our behaviors to the current risk levels.
In my opinion, cases have fallen quickly enough that going back to an ordinary mask is reasonable. Assuming youre not in a crowd indoors or at high risk from COVID.
Is the original COVID strain still infecting people? Are the variants before omicron still infecting people?
Q: What Safety And Effectiveness Data Did Fda Evaluate To Support The Authorization For Emergency Use Of Administration Of A Single Vaccine Booster Dose
A: FDA analyzed safety and immune response data from a subset of participants from the original clinical trial of the Pfizer-BioNTech COVID-19 Vaccine. The immune responses of approximately 200 participants 18 through 55 years of age who received a single vaccine booster dose approximately 6 months after their second dose were assessed. The antibody response against a Wuhan-like SARS-CoV-2 virus one month after a booster dose of the vaccine compared to the response one month after the two-dose primary series in the same individuals demonstrated a booster response.
Safety was evaluated in 306 participants 18 through 55 years of age and 12 participants 65 years of age and older who were followed for an average of over two months. The most commonly reported side effects by the clinical trial participants who received the booster dose of the vaccine were pain, redness and swelling at the injection site, fatigue, headache, muscle or joint pain, and chills. Of note, swollen lymph nodes in the underarm were observed more frequently following the booster dose than after primary series doses.

Progress Report: Why Some People Get Rashes And Sores On Their Toes
COVID-19 is a multi-system disorder, meaning that it can cause problems in almost any part of the body. One of the symptoms that has been reported is a rash that typically develops on the toes within four weeks of testing positive for the virus . Toes can appear red, inflamed and even swollen. For many, the rash is painless but for some it can be excruciating, affecting their ability to wear shoes and walk. It is more common in teenagers and children than adults.
Until recently, the cause was unknown. But now a team of scientists in France believe they have discovered why the virus can cause these unusual symptoms. By looking into 50 cases of COVID toe the researchers were able to show that it was caused by an overreaction of the immune system to the virus.
The immune systems of those affected by the symptom produced higher levels of antibodies which mistakenly targeted their own cells and tissues as well as the invading virus. The rash was a result of the cells lining the tiny blood vessels in the toes being targeted.
The researchers hope their findings will help pave the way for better treatments of those affected by the condition.
They also said that presentation of COVID toe was much rarer after vaccination.
How Could Contact Tracing Help Slow The Spread Of Covid
Anyone who comes into close contact with someone who has COVID-19 is at increased risk of becoming infected themselves, and of potentially infecting others. Contact tracing can help prevent further transmission of the virus by quickly identifying and informing people who may be infected and contagious, so they can take steps to not infect others.
Contact tracing begins with identifying everyone that a person recently diagnosed with COVID-19 has been in contact with since they became contagious. In the case of COVID-19, a person may be contagious 48 to 72 hours before they started to experience symptoms.
The contacts are notified about their exposure. They may be told what symptoms to look out for, advised on when to get tested for the virus, whether and for how long to isolate themselves, and to seek medical attention as needed if they start to experience symptoms.

Why Do Kids Need The Covid
While children and teens may not be as likely to get severely ill from COVID-19, it can still happen and, in fact, the average age of hospitalizations decreased as the oldest members of our communities were vaccinated. With this in mind, parents and teens should consider the following:
- Conditions such as obesity, asthma, and developmental delay, as well as other pre-existing conditions, increase the chance for hospitalization.
- As of mid-October 2021, almost 700 children and teens up to 17 years of age have died from COVID-19.
- As of early October 2021, more than 5,200 cases of multisystem inflammatory syndrome in children have been diagnosed and 50 deaths occurred. MIS-C typically occurs 2 to 6 weeks after having COVID-19, can occur following a mild infection, tends to be more severe in adolescents and teens, and causes about 6 or 7 of every 10 individuals to be placed in intensive care. MIS-C can also affect heart function.
- Finally, this age group can also transmit the infection to more vulnerable family and community members, such as those who are unable to get the vaccine.
Myth: The Ingredients In Covid
FACT: Nearly all the ingredients in COVID-19 vaccines are also ingredients in many foods fats, sugars, and salts.
Exact vaccine ingredients vary by manufacturer. Pfizer-BioNTech and Moderna COVID-19 vaccines also contain messenger RNA and the Johnson & Johnson/Janssen COVID-19 vaccine contains a harmless version of a virus unrelated to the virus that causes COVID-19. These give instructions to cells in your body to create an immune response. This response helps protect you from getting sick with COVID-19 in the future. After the body produces an immune response, it discards all the vaccine ingredients just as it would discard any information that cells no longer need. This process is a part of normal body functioning.
COVID-19 vaccines do NOT contain ingredients like preservatives, tissues , antibiotics, food proteins, medicines, latex, or metals.

Health Benefits Of Vaccination
Vaccination is one of the most effective ways to protect our families, communities and ourselves against COVID-19.
Evidence indicates that vaccines are very effective at preventing severe illness, hospitalization and death from COVID-19, including against Alpha and Delta variants of concern. However, theres a small percentage of the population who are vaccinated that will still be infected with COVID-19 if theyre exposed to the virus.
Evidence indicates that people who are fully vaccinated with an mRNA vaccine are less likely to:
- have COVID-19 with or without symptoms
- spread COVID-19 to others
People who have been fully vaccinated with a viral vector vaccine are less likely to:
- have COVID-19 with symptoms
- spread COVID-19 to others
Vaccination is also the best prevention against post COVID-19 condition. This condition refers to symptoms some individuals experience for weeks or months after being infected with COVID-19. Symptoms can be very different from those during the initial infection.
The condition can affect both adults and children.

Equally Effective Protection With Interval Of 21 Days Or 28 Days Between First And Second Vaccination
Your body produces antibodies after you are vaccinated. 7 to 14 days after the first vaccination with Pfizer or Moderna, 90% of vaccinated people are protected against COVID-19. We do not yet know exactly how long a person remains protected. After a few weeks, antibody levels start dropping and protection becomes less effective. That is why a second vaccination is needed, which you will receive about 4 to 6 weeks after the first vaccination. In response to the second vaccination, your body makes more antibodies that persist for longer and are able to resist the virus more effectively. In terms of protection after the second vaccination, it does not matter whether you receive the second vaccination after 4-6 weeks or a bit later: you are equally well protected.

What Is The Difference Between The First And Second Dose Of The Covid
In the United States, the ingredients in the vial for dose 1 and dose 2 of the same brand are exactly the same. When people talk about dose 1 doses and dose 2 doses, they are just talking about vaccine supply. If you arrive for dose 1 and the person behind you is getting dose 2, they can come out of the same vial.
One vaccine used in some other countries, Sputnik V, has different components in dose 1 and dose 2. Both are adenovirus vector vaccines, but dose 1 uses adenovirus 26 and dose 2 uses adenovirus 5 .
Could The Mrna Vaccines From Pfizer And Moderna Cause The Same Clotting Problem As The J& j Vaccine Did
The Johnson & Johnson /Janssen COVID-19 vaccine is an adenovirus vector vaccine, which is different from the Pfizer and Moderna mRNA vaccines. At the time of the J& J/Janssen pause, more than 182 million doses of the mRNA vaccines had been administered and no cases of thrombosis with thrombocytopenia syndrome, or TTS, had been reported. Three people out of about 85 million doses of Moderna had blood clots, but they did not have low platelets. The number of blood clots experienced by those who got the Moderna vaccine would be expected based on the background rate of clotting in the general population.

How Do Vaccines Work
Vaccines help people develop immunity to a virus or other germ. A vaccine introduces a less harmful part of that germ or something created to look or behave like it into a persons body. The bodys immune system develops antibodies that fight that particular germ and keep the person from getting sick from it. Later, if the person encounters that germ again, their immune system can recognize it and remember how to fight it off.
Coronavirus Disease : Vaccines
There are several COVID-19 vaccines validated for use by WHO . The first mass vaccination programme started in early December 2020 and the number of vaccination doses administered is updated on a daily basis on the COVID-19 dashboard.
The WHO Emergency Use Listing process determines whether a product can be recommended for use based on all the available data on safety and efficacy and on its suitability in low- and middle-income countries. Vaccines are assessed to ensure they meet acceptable standards of quality, safety and efficacy using clinical trial data, manufacturing and quality control processes. The assessment weighs the threat posed by the emergency as well as the benefit that would accrue from the use of the product against any potential risks.
In line with their national regulations and legislation, countries have the autonomy to issue emergency use authorizations for any health product. Domestic emergency use authorizations are issued at the discretion of countries and not subject to WHO approval.
As of 26 November 2021, the following vaccines have obtained EUL:
If you live in a country where vaccines are available to more people beyond these priority groups, get vaccinated as soon as it is your turn.

How The Coronavirus Vaccines Work
The coronavirus has a spike protein on its surface that helps it enter human cells. The coronavirus vaccines help your body make antibodies that recognise this spike protein and can then fight off the virus.
The vaccines contain ingredients that give your body instructions to produce the spike protein, using the virus genetic code.
Then, your body makes antibodies that can recognise the spike protein on the coronavirus if it enters your body and help fight it off. This means that if you choose to take a vaccine, you are less likely to get severely sick if you encounter the coronavirus.
