The Pill is now being marketed as a cancer-preventing tool by researchers at Johns Hopkins University who are exploring whether it’s safe to inject it in women who have been injected with it to prevent breast cancer.
The study is one of the first to assess the effects of the pill in women with a history of breast cancer, and is published in the March issue of the journal The Lancet Oncology.
According to the authors, “the potential for adverse side effects from injection of recombinant human papillomavirus (HPV) vaccines on the immune system are well documented.”
The research team is led by Dr. Annette M. Schaeffer of the Johns Hopkins Vaccine Research Center, who said in a press release: “HPV vaccines are being widely used in the U.S. as a preventive measure against cervical cancer.
This research is one more piece of evidence that HPV vaccines are safe and effective, but we need more research to know if they are effective as well.”
The researchers also note that “no known adverse events were reported in the study, although some women who had received a single dose of recombicase vaccine may have experienced adverse events after vaccination.
This is not an issue we are aware of in this large, multicenter, randomized trial.”
The study included 434 women, including women in their early 20s, who were part of a larger study that had been conducting since 2015.
The researchers tested for HPV DNA, and found no evidence of any HPV DNA present in the women’s saliva.
The vaccine, known as HPV16, was administered in a two-dose, double-blind study with the women in the first year.
In the second year, the women received one dose of the vaccine and a placebo.
A follow-up study was conducted in 2018, with more than 300 women who were in their first year of follow-ups.
The investigators also assessed the efficacy of the HPV vaccine on the women and on the number of new cases of cervical cancer diagnosed and treated in the United States.
In addition, the study included women who received the vaccine with no other medical treatment, including post-partum or post-menopausal women, who are at increased risk for developing cervical cancer and who may have received HPV16 vaccines before their partners became pregnant.
The scientists noted that the researchers are still investigating whether the vaccine could be used to prevent cancer in post-coital HPV16 vaccine recipients.
In a statement, the Johns Wayne University School of Medicine’s Office of Vaccine Safety and Effectiveness said: “The study is a small, observational study with only a few hundred women in it, but it has shown that the vaccine has no significant effect on the risk of cervical cancers.
There are no serious side effects that are likely to occur with the vaccine, and there is no evidence that it can cause a serious increase in cervical cancer.”
A study published in November 2017 found that the pill was safe in women receiving the vaccine in a randomized trial, and that its effectiveness was not significantly different than the standard doses.
The authors noted that “in this study, there were no serious adverse events related to the pill, including nausea, fever, or headache.”
The authors also noted that there was no significant difference in the safety of the three vaccines as compared to the placebo, and they added that there is “some evidence that the doses of HPV vaccine given to women who are not HPV16 vaccinated are less effective at preventing cancer.”
In 2017, the National Institutes of Health funded a study that tested the effectiveness of the combination vaccine of HPV16 and HPV16-containing vaccines.
The two vaccines were administered in combination at three doses.
According, the researchers found that, “given the potential for serious adverse effects after administration of the recombinant vaccine, the vaccine is probably safe for most women, and the vaccine combination has been shown to be safe for women who receive a recombinant HPV vaccine.”
The Johns Hopkins researchers are now continuing to look into the safety and effectiveness of HPV vaccines for post-cancer care.
“This research is important to the development of HPV prevention and care strategies,” Schaefer said in the statement.
“It also underscores the need for more studies of vaccine safety, efficacy, and safety of combination vaccines for cervical cancer prevention.
Vaccines have a long way to go to make them more widely available, but the data now in the Lancet Onctology provides valuable information to support the development and evaluation of vaccines for cancer prevention and to advance the science of vaccine effectiveness.”
