Επειδή έγινε κάποια συζήτηση για την ανάρτηση περί Ιαπωνίας και εκφράσθηκαν ορισμένες αμφισβητήσεις περί της ορθότητας της, παραθέτω το πλήρες αγγλικό κείμενο, ώστε να μπορέσουμε συνολικά να δούμε τι ακριβώς εννοεί.
Το ερώτημα που παραμένει είναι: γιατί μια χώρα αποσύρει τη σύσταση ή "διαφήμιση" όπως το θέλουν μερικοί, ενός εμβολίου (και μάλιστα για ανεπιθύμητες ενέργειες που εκ πρώτης όψεως είναι άνευ ιδιαίτερης σημασίας) ενώ το διατηρεί στο πρόγραμμα εμβολιασμών και ρίχνει έτσι την ευθύνη στους γονείς;
Japan Withdraws HPV Vaccine Recommendation for Girl
Jun 20, 2013
The Japanese government withdrew its recommendation to use human papillomavirus (HPV) vaccines in girls this week, citing concerns from the public about adverse effects, according to news reports.
The announcement is in stark contrast to the pronouncement this week by health officials in the United States that vaccination rates in teenage girls should be increased after a study concluded that estimated vaccine effectiveness is "high."
The Japanese Ministry of Health, Labor, and Welfare is not suspending vaccination, but has instructed local governments not to promote the use of the medicine while analyses are conducted about adverse effects, such as long-term pain and numbness, according to the Japanese newspaper The Asahi Shimbun.
"The decision does not mean that the vaccine itself is problematic from the viewpoint of safety," said Mariko Momoi, who heads a ministry task force looking into the controversy and is a vice president of the International University of Health and Welfare in Ōtawara, Tochigi, Japan. "By implementing investigations, we want to offer information that can make the people feel more at ease."
Merck, which manufacturers and sells one of the vaccines, Gardasil, issued a comment about the Japanese decision.
"While direct causal relationship between the vaccines and serious symptoms observed after inoculation has not been established at this time, we fully understand the anxiety felt by many people in Japan. In response to this decision, we will continue to collaborate with all stakeholders, including (the health ministry), to monitor and verify safety data toward resumption of active promotion for HPV vaccination as soon as possible," according to a company spokesperson quoted in the trade publications Pharmalot.
Both Gardasil, which is a quadrivalent vaccine, and Cervarix (GlaxoSmithKline), which is bivalent, are approved for HPV vaccination in Japan.
GlaxoSmithKline has said that there is "no evidence" that systemic pain is related to Cervarix administration and that the company is providing information to Japanese officials, according to the industry trade Web site BioCentury.
At the same time as the Japanese health authorities were withdrawing their recommendation for HPV vaccination, a top health official in the United States was championing the inoculations.
The endorsement came by way of a study released yesterday by the US Centers for Disease Control and Prevention (CDC), which showed that the vaccine-type HPV prevalence decreased 56% among females 14 to 19 years of age since Gardasil was introduced in 2006.
The results "showing that the types of HPV that commonly cause cervical cancer has dropped by about half in teen girls since 2006 are striking, better than we'd hoped for, and should be a wake-up call for us to increase vaccination rates," CDC der Vaccine?'
In the United States, Gardasil was initially approveirector Tom Frieden, MD, MPH, said during a telephone news conference about the study, as reported by Medscape Medical News.
The news was widely covered by major media, including a feature in The New York Times, entitled Will Parents Still Turn Down an 'Anti-Cancd for females from 9 to 26 years of age, and approval was expanded to boys and men for preventing genital warts and anal cancer caused by certain types of HPV. GlaxoSmithKline's Cervarix is approved for the prevention of HPV in females 9 to 25 years. However, the new CDC study only involved Gardasil.
More From Japan
In Japan, girls will continue to be able to receive the HPV vaccination for free. However, healthcare providers must now inform would-be recipients that the health ministry does not recommend it.
The government's subsidy program for HPV vaccination began in 2010, and an estimated 3.28 million Japanese have received it. According to news reports, 1968 cases of possible adverse effects, including body pain, have been reported.
"We welcome the decision not to recommend the vaccination, even though it is a small step," said Mika Matsufuji, head of a parent group that says their children have suffered adverse effects from the vaccination. "Parents can decide whether their children should receive the vaccination or not," she said.
