How Well Are The Covid
On June 7, the CDC issued a press release regarding their study of the effectiveness of vaccines in fully vaccinated people. The study found that the mRNA COVID-19 vaccines authorized by the Food and Drug Administration reduced the risk of infection by 91% for fully vaccinated people and 81% for partially vaccinated people. The study also is among the first to show that mRNA vaccination benefits people who get COVID-19 despite being fully vaccinated or partially vaccinated .
The results of this study also suggest that fully or partially vaccinated people who become infected with COVID-19 might be less likely to spread the virus to others. With fully or partially vaccinated study participants, the virus was 40% less detectable in their noses. It was also detected in six fewer days as compared to those who werent vaccinated when they became infected.
In addition, people who were partially or fully vaccinated were 66% less likely to test positive for the SARS-CoV-2 infection for more than one week in comparison to those who were unvaccinated. The CDC adds that while these indicators are not a direct measure of a persons ability to spread the virus, they have been associated with a reduced spread of other viruses like varicella and influenza .
How Do I Get A Vaccine Certificate
Once you’re fully vaccinated, you can get your vaccination certificate through Medicare, whether it’s a digital or a hard copy.
Australian residents who are not under Medicare can obtain their immunisation statement through their Individual Health Identifier which can be obtained through the Department of Health website.
It may take time for it to come through, especially if you received a mixed dose.
While ATAGI has recommended using the same COVID-19 vaccine for both doses, some people such as returned travellers have had to receive a different COVID-19 vaccine as their second dose.
According to the Department of Health, individuals that have received a mixed dose schedule can use their Immunisation History Statement as proof of vaccination in the meantime.
Vaccine Breakthroughs And Variants
CDC continues to actively monitor vaccine safety and effectiveness against new and emerging variants for all FDA-authorized COVID-19 vaccines. Research shows that the FDA-authorized vaccines offer protection against severe disease, hospitalization, and death against currently circulating variants in the United States. However, some people who are fully vaccinated will get COVID-19.
The Delta variant is more contagious than previous variants of the virus that causes COVID-19. However, studies so far indicate that the vaccines used in the United States work well against the Delta variant, particularly in preventing severe disease and hospitalization.
Overall, if there are more COVID-19 infections there will be more vaccine breakthrough infections. However, the risk of infection, hospitalization, and death are all much lower in vaccinated compared to unvaccinated people. Therefore, everyone ages 5 years and older should get vaccinated to protect themselves and those around them, including family members who are not able to be vaccinated from severe disease and death.

When Should You Call A Doctor
The CDC urges those who have or may have COVID-19 to watch for emergency warning signs and seek medical care immediately if they experience symptoms including:
- Trouble breathing
- Persistent pain or pressure in the chest
- New confusion
- Inability to wake or stay awake
- Pale, gray, or blue-colored skin, lips, or nail beds, depending on skin tone
“This list is not all possible symptoms,” the CDC states. “Please call your medical provider for any other symptoms that are severe or concerning to you.”
How Do The Vulnerable Get Covid
A vaccination against COVID-19 offers protection against the virus, but it doesnt mean you wont get it. Breakthrough infections infections in people who are vaccinated do sometimes occur.
The good news? Overall, people who are vaccinated are less likely to be infected, notes Dr. Teleron. And if someone does experience a breakthrough infection, their illness is typically milder without the need for hospitalization or ICU care.
Vaccinations also help reduce the spread of the virus, which safeguards your family, friends, colleagues and community.
People with chronic medical conditions may not have as robust of an immune response to vaccines. The COVID-19 vaccine, however, helps protect them against severe disease and death.

What About Future Variants
So far, the preliminary data shows our current vaccines are effective at protecting against circulating variants.
But as the virus mutates, there is increasing chance of viral escape. This means there is a greater chance the virus will develop mutations that make it fitter against, or more easily able to evade, vaccinations.
To help the fight against COVID-19 the best thing we can do is minimise the spread of the virus. This means get vaccinated when you can, ensure you maintain social distancing when required and get tested if you have any symptoms.
Protection And Prevention Go Hand In Hand
Vaccines help slow down the spread of an infectious disease by breaking the chain of infection. Those who are infected eventually have fewer and fewer unprotected people to pass the virus on to. This is how a vaccine increases herd immunity susceptible and not-yet-immunized people are surrounded by a herd of people who have become immune, thanks to vaccination or previous infection. But studies suggest that, for a combination of biological and social reasons, vaccination alone is unlikely to achieve herd immunity against COVID-19 and fully contain the coronavirus.
In fact, vaccination alone can take a long time to eradicate any disease. Even diseases that are nearly eliminated such as chickenpox, measles and pertussis can resurface with waning immunity and declining vaccine rates.
The recent outbreak of infections among the vaccinated New York Yankees shows that vaccinated people not only can still get infected, they might also transmit the coronavirus to close contacts. Highly tested groups, such as professional sports teams, spotlight the fact that mild, asymptomatic infections among the vaccinated in the general population might actually be more frequent than reported. A similar outbreak in airport workers in Singapore shows that, even among the fully vaccinated, new and more infectious variants can spread fast.

When Will I Be Exempt From Restrictions
Not at the moment, but things may change.
National Cabinet has agreed to the plan to re-open Australia and ease restrictions when we meet our vaccine targets.
NSW is expected to be the first state to reach this goal as more than 70 per cent of residents over the age of 16 have now received their first jab.
The NSW government is now on the move to fully vaccinate its residents so that they can lift their lockdown restrictions.
A few other states such as Queensland, Tasmania and Western Australia are reluctant about the national reopening strategy, so it may take some time for every state to reach their vaccine targets and open up their borders.
There will be more information about this when more people are vaccinated, so the best thing you can do now is to encourage your family and friends to get the vaccine.
What To Do If You Think You Have Covid
If you’re fully vaccinated and come into close contact someone who’s tested positive for COVID-19, get tested three to five days after the exposure.
“It’s also recommended that you wear a mask for 14 days after a known exposure whether you have symptoms or not,” adds Dr. Drews.
If you ultimately test positive for COVID-19, you should isolate at home for at least 10 days even if you’re asymptomatic or have only mild symptoms.

Can You Get Covid After Being Vaccinated
Yes. Breakthrough COVID-19 cases happen in people who are fully vaccinated, and they seem to happen more frequently now that the delta variant is circulating widely and immunity may be waning among those who got the vaccine many months ago. All three available coronavirus vaccines are very good at protecting you against severe forms of COVID-19, but they are not 100% effective in preventing infection. Breakthrough COVID can be caused by the delta variant, which is more contagious than some other coronavirus variants.
Most Breakthrough Infections Are Mild
Because people who are vaccinated have had some immunity, some antibodies, a majority of these breakthrough cases are going to be asymptomatic, said Dr. Sanghavi. According to the data, reported by CDC and other publications, it seems like around 25% to 30% of the patients who have had breakthrough infections are completely asymptomatic.
There are about 50% to 60% of the patients who would have some symptoms, but are mild and still may not need hospitalization, he added. “The severity of the symptoms of these COVID breakthrough infection cases would be milder, but in certain patients you may still need all the aggressive care that we provide to an unimmunized person who gets a COVID infection.
For 90% of the patients, the breakthrough infection would be mild, but for 10% of the patients, they would still require hospitalization, said Dr. Sanghavi. But then 1% to 2% of those hospitalized from breakthrough infections may still die, unfortunately. So, its still a concern.
That is the reason why everybody should get vaccinatedbecause even if you are immunosuppressed and get a breakthrough infection, that infection would be mild as compared to a regular infection, he said.

Why Dont We Have Data On Breakthrough Cases
Up until May 1, 2021, the CDC recorded all breakthrough cases, whether mild, moderate, or severe. But starting on May 1, they began recording only breakthrough cases that resulted in hospitalization or death. The CDC explains that they made this change to help maximize the quality of data collected on cases of greatest clinical and public health importance.
But this means that in the U.S. we do not know how often breakthrough cases occur or which variants are causing breakthroughs .
So, should you worry that a fully vaccinated person who may have an asymptomatic breakthrough case can unknowingly transmit the virus to someone who is unvaccinated?
I would say its not likely, but we dont yet know with certainty, says Dr. Meyer. Theoretically, it may be true that people are being infected by their asymptomatic vaccinated contacts, but were just not seeing that clinically, she says. And the verdict is out on this in terms of the epidemiologic data.
Voluntary Reporting By State Health Departments
When the United States began widespread COVID-19 vaccination, CDC put in place a system where state health departments could report COVID-19 vaccine breakthrough infections to CDC.
On May 1, 2021, after collecting data on thousands of vaccine breakthrough infections, CDC changed the focus of how it uses data from this reporting system.
- One of the strengths of this system is collecting data on severe cases of vaccine breakthrough COVID-19 since it is likely that most of these types of vaccine breakthrough cases seek medical care and are diagnosed and reported as a COVID-19 case.
- Persons with asymptomatic or mild cases of vaccine breakthrough infections may not seek testing or medical care and thus these types of vaccine breakthrough cases may be underrepresented in this system. For this reason, CDC relies on a variety of additional surveillance approaches to ensure that it is collecting information on all types of vaccine breakthrough cases.

In our last article we discussed breakthrough infections, which occur when someone who has been vaccinated gets COVID-19. Breakthrough infections lead a lot of people to ask the question, why should I get vaccinated if I can still get COVID-19?
The answer is because if youre vaccinated you will not get as seriously sick and are less likely to die.
In addition, you will help to stop this pandemic. The more people who are infected in a population the higher the prevalence level of the virus and increased risk for everyone. Unvaccinated individuals contribute to the number of people who can possibly get sick and provide a host for COVID-19 to replicate and create more variants. The more the virus spreads, the greater risk of mutation that could possibly be more dangerous than what weve seen so far. While vaccinated people can get COVID -19 and can spread it to others, youre less likely to get COVID-19 if youre vaccinated, and it spreads less easily in vaccinated people.
At this moment, we dont clearly know the long-term affects of COVID-19. But we have already seen some serious side effects for individuals that have had it, including
To get vaccinated:
Vaccines Dont Always Prevent Infection
Fortunately, the vaccines have vastlyoutperformed expectations. For example, in 6.5 million residents of Israel, aged 16 years and older, the PfizerBioNTech mRNA COVID-19 vaccine was found to be 95.3% effective after both shots. Within two months, among the 4.7 million fully vaccinated, the detectable infections fell by 30-fold. Similarly in California and Texas, only 0.05% of fully vaccinated health care workers tested positive for COVID-19.
Vaccine developers often hope that, in addition to preventing illness, their vaccines will achieve sterilizing immunity, where the vaccination blocks the germ from even being able to get into the body at all. This sterilizing immunity means someone whos vaccinated will neither catch the virus nor transmit it further. For a vaccine to be effective, though, it doesnt need to prevent the germ from infecting an immunized person.

“A person with COVID-19 is considered infectious starting two days before they develop symptoms, or two days before the date of their positive test if they do not have symptoms,” according to the CDC.
Regardless of symptoms, those who test positive are advised to take specific precautions for at least 10 days.

Defining The Vaccinated Vulnerable
The vaccinated vulnerable includes a wide range of people, starting with older adults . The list also includes:
- Cancer patients and others who are immunocompromised.
- Those with dealing lung disease , heart disease and rheumatological conditions.
- Organ transplant recipients, especially those receiving immunosuppressive therapy.
- Anyone taking immunosuppressants or long-term steroids for treatment.
Its Still Good To Be Cautious
While this is encouraging news, Dr. Cardona stresses that fully vaccinated people still need to be careful as everything opens up again.
Virus transmission may still occur from those who are infected and asymptomatic, or ill without knowing it, especially in crowded areas with a lack of physical distancing, respiratory precautions and hand washing. Other factors to consider are ongoing community transmission and immunization rates.
If you havent been vaccinated or havent completed the vaccination series, she recommends doing so. And if you have a unique circumstance that delays your ability to complete your series of shots as scheduled, still get the second dose. Dr. Cardona says restarting the series isnt necessary.
The CDC also recommends that fully vaccinated people wear masks indoors in public for maximum protection from the delta variant and to lessen the risks of transmission. You should also wear a mask if you have a weakened immune system, an underlying medical condition or are at high risk for severe disease.

What Should I Do If I Have Been Exposed To Covid
If youre fully vaccinated and have also received your booster , you do not need to quarantine, but you should wear a mask for 10 days following exposure and test for COVID-19 at day 5 after exposure. If its been 6 months or more or 2 months or more since completing your primary vaccine series, and you have not yet received a booster dose, you must quarantine for 5 days, followed by strict mask use for an additional 5 days. Everyone should get tested at day 5 after exposure, regardless of vaccination status.
Why Are So Many Vaccinated People Getting Covid
Why are so many vaccinated people getting COVID-19 lately?
A couple of factors are at play, starting with the emergence of the highly contagious omicron variant. Omicron is more likely to infect people, even if it doesnt make them very sick, and its surge coincided with the holiday travel season in many places.
People might mistakenly think the COVID-19 vaccines will completely block infection, but the shots are mainly designed to prevent severe illness, says Louis Mansky, a virus researcher at the University of Minnesota.
And the vaccines are still doing their job on that front, particularly for people whove gotten boosters.
Two doses of the Pfizer-BioNTech or Moderna vaccines or one dose of the Johnson & Johnson vaccine still offer strong protection against serious illness from omicron. While those initial doses arent very good at blocking omicron infection, boosters particularly with the Pfizer and Moderna vaccines rev up levels of the antibodies to help fend off infection.
Omicron appears to replicate much more efficiently than previous variants. And if infected people have high virus loads, theres a greater likelihood theyll pass it on to others, especially the unvaccinated. Vaccinated people who get the virus are more likely to have mild symptoms, if any, since the shots trigger multiple defenses in your immune system, making it much more difficult for omicron to slip past them all.
