Does The Covid Vaccine Prevent Spread

When Can I Get The Coronavirus Vaccine

Coronavirus Q& A: Vaccine defence against asymptomatic spread

Now that the Food and Drug Administration has issued emergency use authorizations for COVID-19 vaccines, vaccines are being distributed across the United States.

If you are a Johns Hopkins Medicine patient, visit our COVID-19 Vaccine Information and Updates page for current information on getting vaccinated. Your states health department website can also provide updates on vaccine distribution in your area.

Myth: The Mrna Vaccine Is Not Considered A Vaccine

FACT: mRNA vaccines, such as Pfizer-BioNTech and Moderna, work differently than other types of vaccines, but they still trigger an immune response inside your body.

This type of vaccine is new, but research and development on it has been underway for decades.

The mRNA vaccines do not contain any live virus. Instead, they work by teaching our cells to make a harmless piece of a spike protein, which is found on the surface of the virus that causes COVID-19. After making the protein piece, cells display it on their surface. Our immune system then recognizes that it does not belong there and responds to get rid of it. When an immune response begins, antibodies are produced, creating the same response that happens in a natural infection.

In contrast to mRNA vaccines, many other vaccines use a piece of, or weakened version of, the germ that the vaccine protects against. This is how the measles and flu vaccines work. When a weakened or small part of the virus is introduced to your body, you make antibodies to help protect against future infection.

Personal Account: My Niece And Nephew Contracted Covid

Three weeks ago, I got a call from my sister telling me that both my niece and nephew had tested positive for COVID-19. Aged 11 and nine respectively, both are too young to qualify for the vaccines here in the UK. My sister and her husband are fully vaccinated, so I told her that even though they may still get the virus, it is likely they would only suffer mild symptoms. Her main concern, however, was for the children while my niece was just mildly tired and had a blocked nose, my nephews symptoms were more significant.

My nephew, Ben, is a well child. He is lucky not to suffer from any underlying health conditions and keeps himself fit by playing for the local football club. But he had come home from school in tears, complaining of a headache and pain in his legs. While the latter symptom dissipated, the headache continued and kept him awake at night. He became overwhelmed by fatigue and was struggling to get out of bed. This lasted for a week and was accompanied by frantic phone calls from my sister, asking me if there was anything that could alleviate his distress.

It was nearly two weeks before he began to feel better, and during that time not only was he missing school and vital education, he was also suffering. It made me think about all the children who were contracting COVID in school and for whom the illness was not a mild one.

Vaccinated People Are Less Infectious Better Protected

Biden is correct that COVID-19 is primarily a disease of the unvaccinated when we look at hospitalizations and deaths, said Dr. Paul Offit, director of the Vaccine Education Center and an attending physician in the Division of Infectious Diseases at Children’s Hospital of Philadelphia.

However “vaccinated people can shed virus and be contagious but generally shed virus in lower quantities and for a shorter amount of time.” Offit pointed to a study from Singapore which found that vaccinated individuals who caught COVID-19 “had a more rapid decline in viral load, which has implications on secondary transmission and public health policy.” The study was done based on cases earlier this year before omicron emerged.

Brooke Nichols, a health economist and infectious disease mathematical modeler at Boston University, said “vaccinated individuals can definitely infect other people. There is enough data to support this.”

“While vaccinated individuals may be less infectious and infectious for a shorter duration of time they are by no means a dead-end host,” Nichols said. “When calling it a pandemic of the unvaccinated, though, it makes it sound as those vaccinated individuals arent substantially contributing to new cases which they are . Unvaccinated individuals do, however, continue to contribute disproportionately to hospitalizations and deaths.”

The Faster Safer Lower Cost Way To End The Pandemic

Vaccine Information

Everyone needs to stop listening to the CDC now and start listening to people who have been saying to ditch the vaccines and aggressively promote early treatment with repurposed drugs.

The entire pandemic will end as soon as the CDC stops ignoring the existing early treatment protocols which have been available since March 2020 . Masking, vaccines, mandates, lockdowns, and social distancing were never needed. We could have end the hospitalization and death with just one thing: early treatment. Just like Japan has done. But the CDC refused to listen.

If Vaccines Stop Covid Spread What Does That Mean For Us

The best-case scenario is the COVID-19 vaccines completely stop transmission, and once we get enough of the population vaccinated, the virus has no-one left to infect and tapers off to nothing.

Sounds great, doesn’t it?

“If we do have vaccines that allow prevention of transmission, this really does change the game in terms of our international travel, our lockdowns and the way we think about the virus,” Professor McMillan says.

If we could eliminate the virus completely, we would not have to worry about updating future vaccines to shield us from new COVID variants that may evolve to elude current jabs, Dr Labzin says.

“But it’s pretty hard to do. Even though we’ve had all these vaccines for different things for many years, smallpox is the only one we’ve managed so far,” she says.

“It just goes to show that’s a really huge goal and it’s probably not necessarily achievable .”

Besides, it is highly unlikely any of our current crop of COVID-19 vaccines will provide sterilising immunity.

While early trials showed the vaccines reduced the amount of virus in animals’ lungs, none of the jabs completely eliminated it from their system, Professor Lewin says.

“I think it’s because it’s so easy to infect the nose there are so many receptors for the virus there,” she says.

“But next-generation vaccines may well induce sterilising immunity.”

What Can I Do To Protect Myself And Others From Covid

The following actions help prevent the spread of COVID-19, as well as other coronaviruses and influenza.

If you are not fully vaccinated against COVID-19:

  • Wear a face mask, as advised by the CDC.
  • Maintain at least six feet of distance between yourself and others.
  • Avoid large gatherings.
  • Get vaccinated as soon as you are eligible.


  • Wear a mask in public indoor spaces in areas with widespread transmission of the SARS-CoV-2 virus.
  • Avoid close contact with people who are sick.
  • Minimize touching your eyes, nose, and mouth.
  • Stay home when you are sick.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean frequently touched objects and surfaces regularly.
  • Wash your hands often with soap and water.

This chart illustrates how protective measures such as limiting travel, avoiding crowds, social distancing, and thorough and frequent handwashing can slow down the development of new COVID-19 cases and reduce the risk of overwhelming the health care system.

The Stunning Conclusion Of The Paper

In light of the exponential rise in Omicron cases, these findings highlight the need for massive rollout of vaccinations and booster vaccinations.

All I can say is wow. The people who wrote this paper are clearly drinking the Kool-Aid on their interpretation of what their study means.

They also wrote this :

The negative estimates in the final period arguably suggest different behaviour and/or exposure patterns in the vaccinated and unvaccinated cohorts causing underestimation of the VE. This was likely the result of Omicron spreading rapidly initially through single events causing many infections among young, vaccinated individuals.

This paper should be a wake up call: the vaccines do not work. Stop repeating the insanity.

Early treatments like the Fareed and Tyson protocol are 10X better than any new therapy, they dont hook you, and they dont cause disability or death.

If doctors started prescribing the Fareed and Tyson protocol, wed have virtually no deaths, and few hospitalizations. But they cant do that since medical board will take away the licenses of any physicians who prescribe ivermectin, etc. This is happening now.

Vaccines Decrease Chances Of Infection Transmission

UK and Israel study show COVID-19 vaccine may prevent spread and protect from severe illness

All three COVID-19 vaccines authorized in the U.S. were designed to prevent severe infection, hospitalization and death. But experts and public health officials say the shots also protect people from contracting and spreading the virus.

“What we know is that individuals who are vaccinated are much less likely to be infected therefore much less likely to spread the virus,” Dr. Amesh Adalja, a senior scholar at the Johns Hopkins Center for Health Security, said in an email.

Data from clinical trials indicate the vaccines from Pfizer-BioNTech and Moderna are about 95% effective at preventing symptomatic COVID-19 infections. Johnson & Johnson’s shot was found to be about 72% effective at preventing moderate to severe disease.

The vaccine rollout has affirmed those findings.

Fully vaccinated people made up about 9% of reported COVID-19 deaths in 13 U.S. jurisdictions between April and July, according to the Centers for Disease Control and Prevention. CDC studies have also shown unvaccinated people are 10 times more likely to be hospitalized with COVID-19.

Fact check:Infected with COVID-19 in the past? You still need the vaccine, experts say

The agency says on its website that, while breakthrough infections are possible, “most people who get COVID-19 are unvaccinated.” Experts told USA TODAY the shots provide considerable protection against infection and transmission.

Data on how COVID-19 vaccination affects transmission is more complicated, but still promising.

What You Need To Know

  • The benefits of COVID-19 vaccination outweigh the known and potential risks, which are rare.
  • As with other routine vaccines, side effects may occur after vaccination. These are normal and should go away within a few days.
  • People who are fully vaccinated can resume many activities they did before the pandemic. However, people should wear a mask indoors in public if they are in an area of substantial or high transmission.
  • If you received a Pfizer-BioNTech or Moderna mRNA COVID-19 vaccine primary series and have a moderately or severely compromised immune system, you should receive an additional primary dose of the same mRNA COVID-19 vaccine at least 28 days after the second dose.
  • Everyone ages 16 years and older can get a booster shot.
  • Unlike many medications, COVID-19 vaccine dosage does not vary by patient weight but by age on the day of vaccination.
  • People can get a COVID-19 vaccine and other vaccines, including flu vaccine, at the same time.

Stay At Home When You’re Sick

You should continue to stay at home when you’re sick. This will help reduce the risk of spreading COVID-19 and other illnesses.

Follow the instructions of your local public health authority on COVID-19 quarantine or isolation requirements.

If you develop symptoms of COVID-19 and you’re outside your home, you should:

  • put on a medical mask or consider using a respirator
  • if unavailable, properly wear a well-constructed and well-fitting non-medical mask that includes a filter layer
  • isolate yourself away from others as quickly as possible
  • contact your health care provider or local public health authority and follow their advice
  • Be prepared to stay at home if you have symptoms of COVID-19 or need to care for someone who is sick.

    If your illness or symptoms aren’t COVID-19 related, consult with your health care provider to determine when you can return to regular activities.

    The Risk Of Vaccinated Covid Transmission Is Not Low

    After my son got sick, I dived into the data, and it turns out vaccinated people can and do spread COVID

    My two-year-old tested positive for COVID last month. My mind-numbing and costly project to keep him uninfected prior to his vaccinations had proven an abject failure. I was angryand surprised. During the time he was likely infected, he had only been around vaccinated people when indoors.

    Although we know the absolute risk of serious illness in young children is low, there are many other causes for concern as a result of unvaccinated infection: multisystem inflammatory syndrome 00324-2/fulltext” rel=”nofollow”> brain damage, psychiatric or chronic disease later in life, and damage to smell. While Ill never know exactly who infected my son, his infection drove me to discover something that only came into focus in late October: the risk of vaccinated transmission is notlow.

    If I could do things over again, I would not have allowed my son to be around even vaccinated people indoors without masks.

    Early Data Looked Promising


    Although the vaccine manufacturers did not track infections for all phase three trial participants, they did gather some data. Moderna tested all participants when they received their second dose and reported in December that fewer asymptomatic infections occurred in the vaccinated group than the placebo group after the first dose. Johnson & Johnson also reported data from nearly 3,000 phase three trial participants who were tested two months after vaccination to see if they had antibodies from a new infection since vaccination. That preliminary data suggested a 74 percent reduction in asymptomatic infection.

    Those findings hinted that the vaccines had the ability to prevent infections. That development was followed by three preprintsnot yet peer-reviewedthat suggested even more good news. One found that people vaccinated with one dose of the Pfizer-BioNTech vaccine had viral loads up to 20 times lower than viral loads in unvaccinated, infected people.

    Two others, from the Mayo Clinic and the U.K., included more than 85,000 routinely tested healthcare workers who were fully vaccinated with the Pfizer-BioNTech vaccine. The vaccine reduced infection by 85 to 89 percent. All this evidence underscores all three vaccines ability to prevent infection in the majority of those vaccinated.

    What Is Physical Distancing And Why Is It Important

    The COVID-19 virus primarily spreads when one person breathes in droplets or aerosols that are produced when an infected person coughs, sneezes, talks, or breathes.

    Physical distancing refers to actions taken to stop or slow down the spread of a contagious disease. For an individual, it refers to maintaining enough distance between yourself and another person to avoid getting infected or infecting someone else. Directives to work from home, and cancelling meetings and larger events help enforce physical distancing at a community level.

    Is There A Vaccine For The Coronavirus Disease

    Several COVID-19 vaccines have been authorized for emergency use among specific age groups by the U.S. Food and Drug Administration . Johns Hopkins Medicine views all authorized COVID-19 vaccines as highly effective at preventing serious disease, hospitalization, and death from COVID-19.

    If I Want To Visit Friends And Family Does It Matter Whether We Meet Indoors Or Outdoors

    You are better off meeting friends and family outdoors. We know that coronavirus spreads when someone breathes in virus that an infected person emits through coughs or sneezes, or when they talk or breathe. Research has shown that in a confined, laboratory setting, droplets containing viral particles can remain afloat for eight to 14 minutes. Smaller infectious viral particles, called aerosols, can drift around in the air even longer.

    Outdoors, air currents are more likely to scatter and dilute the virus, making transmission less likely than in a home, office, or other confined space with limited air circulation. Even outdoors, if you are not fully vaccinated, follow CDC guidance on masking and physical distancing, to reduce risk even further.

    Covid Vaccines Probably Prevent Spread

    How Do the COVID Vaccines Impact Variant Spread?

    The evidence is preliminary, but it looks like the COVID vaccines do reduce the risk of spread of SARS-CoV-2.

    The Centers for Disease Control recently published their updated recommendations for precautions by people who are fully vaccinated against COVID-19. They needed to review available data on the efficacy of the available vaccines in the US Pfizer and Moderna J& J is just coming out. Their recommendations are welcome news to those who are fully vaccinated, which means you have received your second dose of vaccine more than two weeks ago .

    Their recommendations are, in non-health care settings, and for those who are not at high risk:

    • Visit with other fully vaccinated people indoors without wearing masks or physical distancing
    • Visit with unvaccinated people from a single household who are at low risk for severe COVID-19 disease indoors without wearing masks or physical distancing
    • Refrain from quarantine and testing following a known exposure if asymptomatic

    Studies for the H1N1 flu vaccine, for example, show that they reduce shedding of virus and delay but do not completely eliminate transmission to unvaccinated subjects.

    In the original studies used to show efficacy of the Moderna vaccine, they also gathered secondary data on the prevention of asymptomatic infections. They found:

    A single dose of BNT162b2 vaccine demonstrated vaccine effectiveness of 72% 21 days after first dose and 86% seven days after two doses in the antibody negative cohort.
