Nothing in medicine is 100% safe – even something we take without thinking, like paracetamol, poses risks. 

כמו כל התרופות, חיסון זה עלול לגרום לתופעות לוואי, אם כי לא כולם מקבלים אותן. במחקרים קליניים עם החיסון, מרבית תופעות הלוואי היו אופי קל עד בינוני ונפתרו תוך מספר ימים, כאשר חלקן עדיין נוכחות שבוע לאחר החיסון. 

אם תופעות לוואי כגון כאב ו / או חום מטרידות, ניתן ליטול תרופות המכילות אקמול. אבל תמיד דבר קודם עם רופא.

Tell your doctor, pharmacist or nurse before vaccination: 

• If you have ever had a severe allergic reaction (anaphylaxis) after any other vaccine injection;  
• If you currently have a severe infection with a high temperature (over 38°C). However, a mild fever or infection, like a cold, are not reasons to delay vaccination;
• If you have a problem with bleeding or bruising, or if you are taking a blood thinning medicine (anticoagulant); 
• אם מערכת החיסון שלך אינה פועלת כראוי (חסר חיסוני) או אם אתה נוטל תרופות המחלישות את המערכת החיסונית (כגון סטרואידים במינון גבוה, מדכאי חיסון או תרופות לסרטן). 

אם אינך בטוח אם אחד מהאמור לעיל חל עליך, שוחח עם הרופא, הרוקח או האחות לפני שקיבלת את החיסון.
